Advice 1: How to grow crystals of copper sulfate

Crystals have always been a curiosity and amazement. Nature itself took care of the phenomenon of their growth, resulting in formation of crystals bizarre shapes. It is possible to grow crystals of copper sulphate alone at home, especially since the reagent required for this is so common that there is almost in every house. Is copper sulfate, which has a crystalline blue color, and its anhydrous salt is pale blue. For growing crystals are perfect for both.
How to grow crystals of copper sulfate
You will need
  • The glass plate or saucer, copper sulfate, clearcoat
Instruction
1
Buy copper sulfate, or copper sulfate can be in any shop for repairs or gardening, because the purpose of copper sulphate in the spraying of trees and shrubs from pests. There is no need to use specialized chemical utensils, and all the laboratory manipulations can be performed in an ordinary Cup and saucer.
2
First preparing primary saturated salt solution. To do this, take half a Cup of hot water and dissolve half a teaspoon of copper sulphate. After complete dissolution of the repeat dissolution of salt until then, until it ceases to dissolve. Thus, you get a saturated solution of copper sulphate.
3
To the crystals was beautiful and clean, it is necessary the mixture is filtered, and as quickly as possible, before the crystallization. The filtrate obtained is poured into a saucer and cover glass (you can not cover it up, but if dust or insects into the solution will be contaminated and eventually the crystals will lose their purity).
4
Through the day, and perhaps earlier, it is already possible to observe the precipitated small crystals. They appear a lot, and some of them are clusters, and some single trees. It is the latest diamond crystals and need to pay attention. For further work it is necessary to choose crystals most correct form without any inclusions or impurities.
5
Then again, preparing a solution of copper sulphate, which is now called the fallopian, and in a similar way. The filtrate obtained is poured into a saucer or plate and carefully placed it the selected crystals in an amount of from 2 to 5 pieces. An important condition is them distant from each other location, or during their own growth they can talk among themselves and then the formed crystals will not work. Then close the capacity of the glass and from time to time prepare a new stock solution and carefully pour to the previous one, in which the younger crystals.
6
Takes a few weeks to grow crystals of copper sulphate in the form of a beautiful diamond-shaped formations of saturated blue. Just need to remember that the product is very fragile and gradually loses water, becoming a soft powder blue color is the anhydrous salt, that is, in other words is the destruction of the crystals. So in order to preserve their cover with a colourless varnish.
7
Similarly, we can obtain the "miracle stone" on the thread, if you just position the original obtained crystals along the bone on the bottom of the dish. The end result is self-made necklace of blue jewels. The grown crystals can be a subject of pride of their own achievements in the field of chemistry.
Useful advice
If you want to get a single, correct form of the crystals, ensure that during topping up the solution on the major crystals are not dropped new smaller crystals.

Advice 2 : How to make a crystal of copper sulphate

Blue crystals of copper sulfate are extremely beautiful. Experience in cultivation may be a long time to interest your preschooler and even the school child will love to watch grow on the string of crystals. For high school student this can serve as an introduction to one of the most interesting science — crystallography.
Crystals of copper sulphate - the first step to the science of crystallography
You will need
  • Copper sulphate
  • Water
  • Filter paper
  • Thread cotton
  • Magnifier
  • Tweezers
  • Glassware for solution preparation
  • Transparent glass vessel-mold
  • Cover glass
  • Flat stick whose length is greater than the diameter of the neck of the vessel
Instruction
1
Heat water to 45-50°C. Prepare a saturated solution of copper sulphategradually dissolving the powder in water until the complete cessation of further dissolution. Filter the resulting solution through filter paper and pour it into the mold.
2
To a stick, tie a cotton thread. Lower the thread about half the container of solution. Cover the vessel with a cover glass so no dust. But you need to cover is not very tight, because the vessel needs to get air.
3
Put the pot in a quiet place about a day. During crystal growth the solution can not be shake and shake. This can lead to the dissolution of already formed crystals. A day with a magnifying glass, consider formed on the threads and on the bottom of the vessel crystals. Select the largest and correct. Carefully using tweezers, remove the rest. Leave 4-5 crystals, and the distance between them should be sufficient for their growth. The crystals must not touch or they will stick. In the future, with the growth of the crystals to make sure that time they had not formed a new one. In the crystallizer it is impossible to add the solution.
Note
Copper sulphate for this experience you need to buy at the store chemical reagents or at the pharmacy. The package must be marked "CH", "GRADE" or "analytical grade". Copper sulfate, which is sold in agricultural stores, in this case not necessary.


Vessels experience must be from chemical glass

The crystallizer must be protected from extreme temperatures, dust and foreign objects. In any case can not touch the surface of the crystals by hand.
Useful advice
Water for crystal growing is better to take distilled

Vessel you have a wide neck.

Advice 3 : How to grow a crystal of copper sulphate

In nature, there are many crystals of different shapes and colors. For example, precious stones (diamond, emerald, ruby, etc.), frost on the branches of trees, snowflakes, etc. Some species of mollusks have the potential to build a mother of pearl on foreign bodies caught in the sink. Resulting in a pearl. Crystals can be grown at home.
How to grow a crystal of copper sulphate
You will need
  • - clean dishes;
  • - sulphate of copper (blue vitriol);
  • water;
  • sticks and thread;
  • filter.
Instruction
1
For growing a large single crystal of sulphate of copper will buy the copper sulfate powder. It can be purchased at any hardware store or in those outlets that sell fertilizer for plants.
2
Then prepare a saturated solution of copper sulfate (II). To do this, take a clean container (beaker, flask or any other), fill it with water. Then sprinkle salt in small portions. Mix thoroughly. You need to halt the dissolution of the salt. Note that at room temperature the preparation of a saturated solution may take a day or two. But you can accelerate this process by heating the mixture in a water or sand bath for about three hours.
3
Once you've obtained a solution of the desired concentration, cool it (if used a method by heating) and filter through filter paper or cotton. On the filter remains a crystalline residue. From it, select one well-formed crystal.
4
Attach the chosen crystal to a string, tie it to a stick, a pen or pencil. Then dip the seed in a container with a filtered solution, and leave for a few days. Have patience, because the size of the stone depends on the time spent in the solution.
5
Once the crystal has reached your desired size, remove it and gently dry it with a napkin. To prevent the destruction of your grown miracle, cover it with varnish, which will prevent the evaporation of water.
6
Ensure that the solution is not a precipitate formed. If this happens, filter the liquid into a clean Cup and transfer to the growing crystal.
Note
To the vessel, with the growing crystal is not exposed to dust, close it with gauze.
Useful advice
Keep in mind the chip is very fragile and can easily break.

Advice 4 : How to grow crystals of copper sulfate

To grow crystals of copper sulfate can home. The basis for cultivation is a supersaturated solution of copper sulphate. For the formation of the crystal will require priming. You can use any properties of the foreign object (for example, copper wire) or wait until the bottom of the vessel formed crystal. Time and quality of crystallization depends on purity of copper sulfate and temperature of the solution.
How to grow crystals of copper sulfate
You will need
  • - sulphate of copper (blue vitriol, CuSO4);
  • heat - resistant glass chemical flask or glass jar;
  • - the seed on a string (a piece of copper wire);
  • - sandpaper;
  • - a sheet of paper;
  • - rod from a ball pen;
  • - gauze;
  • - rubber gloves;
  • - distilled or boiled water.
Instruction
1
Prepare all the necessary materials. It is best to purchase as clean as possible copper sulfate, which is sold in stores with the reagents (grade analytical grade, reagent GRADE, CHA). If this is not possible, use copper sulfate from the hardware store. The more pure the stuff you use, the better will be the crystals. You still need a heat-resistant glass chemical flask, to dissolve this substance. Suitable and conventional small jar of glass, for example, 0.7 or 1 l. Before use, wash very carefully selected capacity.
2
If you use pure copper sulphate from the store of reagents for best results, take distilled water. For conventional copper sulfate from the hardware store will fit boiled.
3
Now you need to make a saturated solution. Heat water to 60-70 degrees. Gradually add the sulphate of copper, immediately stirring him. Do that until, until the blue powder will no longer dissolve, this means that the solution is ready. It is important that the liquid remained hot. If it is cold, place the vessel in a water bath and heat the solution.
4
When a saturated solution is ready, filter it. To do this, strain the liquid through cheesecloth into another glass container. Use hot glass dish, otherwise the copper sulphate may crystallize ahead of time. To avoid this, simply rinse jar or beaker with hot water.
5
As a seed you can use a piece of copper wire. Clean it with emery paper, roll to desired shape and tie him to the thread. Or you can wait until the bottom of the jar with a saturated solution of the formation of small crystals of copper sulphate, and have them to use as starters.
6
Crystals will appear on the bottom of the vessel by themselves, if the solution has a sufficient concentration. Get them dry. As a seed it is better to use the large and smooth entity, preferably without external defects. Tie it with thread. If it slides off, you can slightly grind the crystal in the middle, making a notch.
7
Place a seed crystal from crystal or copper wire into the banks so that the sinker does not touch the walls or bottom of the vessel. To do this, you can bind a string to the rod of a ballpoint pen and put it on the neck. Now cover the jar with paper and leave for a few days.
Note
Concentrated copper sulphate is toxic, so work with him in rubber gloves. In no case should not drink the resulting liquid. Drops should not fall on the skin. If the solution gets into eyes, rinse and consult a doctor.
Useful advice
If you want to save the resulting crystals of copper sulphate, cover them with colourless varnish, otherwise they will erode.

Advice 5 : How to grow crystals of copper kuporosa

Vitriol (from the French. couperose) – a General name for crystalline hydrates of sulfates of divalent metals. Copper sulphate – blue pentahydrate consisting of sulfate, honey and water molecules. It has chemical formula CuSO(4)•5H(2)O.
How to grow crystals of copper kuporosa
You will need
  • - sulphate of copper;
  • water;
  • - a glass;
  • - a thread;
  • - gauze or filter paper;
  • - sand bath;
  • spoon for stirring;
  • - ceramic tiles;
  • - Petri dishes or glass cover.
Instruction
1
Create a saturated solution of copper sulphate. 200 ml of water at 20oC is required not less than 72 g CuSO(4). A small crystal of salt will attach to the thread and drop a seed into the solution. Cover the container with gauze or filter paper. Allow the solution to slowly evaporate at room temperature. This method to grow the crystal is quite long, it can take weeks or even months.
2
With increasing temperature water solubility of copper sulfate increases. But since 80 ° C is little change. Pour 300 ml water into a large glass, add 200 g of copper sulfate, put on a sand bath, heat. From time to time stir the solution until all the salt is dissolved.
3
Remove from sand bath beaker, place on a ceramic tile and allow the solution to cool. Make a seed – crystal of sulphate of copper on a string. The seed can be dissolved, but it doesn't matter. The bulk of the copper sulfate will precipitate.
4
Remove the thread from the solution, repeat the procedure. Again heat the beaker on a sand bath until the precipitate dissolved. Turn off heat, cover with a glass Petri dish or just a glass lid, wait for a while.
5
Make the solution a seed crystal, cover glass, and leave overnight. The morning thread is formed on the crystal size 5 cm This is a quick way to grow a crystal of copper sulfate.
6
The fast method seed does not matter, you can omit even the "empty" string. The remaining after the experience of the use solution for slow growing large crystals.
Useful advice
If you want to grow a big beautiful crystal, closely related to the selection of the crystal for starters. Try to find a well-formed, strong, with no external injuries.
