Advice 1: How to neutralize sulfuric acid

Sulfuric acid is among the five most strong acids. The necessity of neutralization of the acid occurs, in particular, in the case of leakage and when there is a threat of poisoning her.
How to neutralize sulfuric acid

A molecule of sulphuric acid consists of two atoms of oxygen and sulfur dioxide. It is a liquid, which is colorless and odorless, but have a high viscosity. Concentrated sulfuric acid has the consistency of oil. In the liquid state it may be at a temperature not exceeding 300 degrees. At a temperature of 296 degrees it starts to decay. It can also be mixed with water. Sulfuric acid is very toxic and causes burns on the skin. In dissolved form it neutralizes alkalis, ammonia hydrate.

Also sulfuric acid capable of reacting with sodium hydroxide. Concentrated sulfuric acid is diluted by one portion of NaOH:

H2SO4 (conc.)+NaOH=nahso4 solution+H2O

For diluted sulfuric acid requires the same lye in a double size:

H2SO4 (highest.)+2NaOH=Na2SO4+H2O

In both cases, neutralization of the formed oxazole. Na2SO4 is a white substance, so in the neutralization of sulfuric acid, precipitation of a white precipitate.

Additionally, sulfuric acid can interact with sodium hydroxide. Concentrated sulfuric acid is diluted by one portion of NaOH:

H2SO4 (conc.)+NaOH=nahso4 solution+H2O

For diluted sulfuric acid requires the same lye in a double size:

H2SO4 (highest.)+2NaOH=Na2SO4+H2O

In both cases, neutralization of the formed oxazole. Na2SO4 is a white substance, so in the neutralization of sulfuric acid, precipitation of a white precipitate.

In addition, sulphuric acid under certain conditions neutralizes oxides of some metals. So, for example, diluted sulfuric acid combines with oxide of barium, forms a salt - barium sulfate and water:

H2SO4 (highest.)+BaO=BaSO4+H2O

Some metals, such as zinc, react well with dilute acid to form salt and hydrogen excreted:

H2SO4 (highest.)+Zn=ZnSO4+H2

Advice 2: How to get sulfuric acid

Chemistry is one of the most important fields of natural science, and one of the main substances, which is unthinkable without this science is sulfuric acid. It finds application in virtually any chemical process. Simply put, sulfuric acid is the Queen of chemistry.
How to get sulfuric acid
You will need
  • Battery electrolyte, glass jar, saucepan, engine oil, electric.
Instruction
1
In industry it is obtained by dissolving sulfur trioxide (sulphur trioxide) in water. And for dioxide, sulfur dioxide formed, for example, after roasting sulphide ore or obtained by direct method (by burning sulphur in oxygen), oxidize to sulfuric anhydride at a temperature of 500 degrees centigrade for the catalysts of platinum, vanadium oxide, and the like. But, what would you get concentrated sulfuric acid in the handicraft way, not necessarily to resort to the above trick. In the automotive store to buy a battery electrolyte, take an ordinary glass jar and pour it in there, then take the pan, pour in the motor oil (it will come down and practicing) and put there the jar. Then everything is placed on the stove.

Thus, there is evaporation of water from the electrolyte. Trick oil bath is that the temperature of boiling oil is somewhat larger than the boiling point of water and thus the water quietly boils and the butter is not boiling and the glass jar is intact, as is heated uniformly over the entire area. Even hot concentrated sulfuric acid does not react with glass, so the amount of impurities in it is minimal. The process can be carried out in the temperature range from 100 to 300 degrees, but it is better not exceed the boiling point of the oil. Continue the process until until water boils away. In principle, concentration of sulfuric acid can be produced in a solid metal container, but after that the acid is heavily contaminated with impurities and will have a darker color, and besides, it is likely that the capacity in the process will leak.
Note
Avoid sudden temperature changes, this applies to glass jars, ie don't put a cold jar into the hot oil and the hot jar on a cold surface, allow to cool completely, otherwise it will burst for sure. Be sure to protect eyes, skin, clothing, wear gloves, goggles and other means. Hot concentrated sulfuric acid is quite a terrible thing.
Useful advice
Automotive stores in addition to the standard electrolyte density 1,27 sold density of 1.4, take it, the yield will be more. To do these things preferably on the air, as when heated the oil is a little to smoke.

Advice 3: How to neutralize phytic acid in cereals

As soon as it comes about healthy eating or losing weight, all the first to remember about the benefits of oatmeal. However, due to its high concentration in phytic acid nutritionists advise to drink oatmeal more often than 2 times a week. Because this insidious acid "steals" calcium from the body.
How to neutralize phytic acid in cereals

In fact, phytic acid contained not only in oatmeal. Any whole grains, legumes, raw seeds and nuts, wheat germ abound in this antinutrient. Especially a lot of phytic acid in the bran. I must say that the above are the most useful, healthy foods is essential to everyone. But everything is good in moderation. We proceed to the detriment of phytic acid begins only when accumulated in the body a fair amount.

It interacts, if it failed to neutralize in the process of cooking food, in the intestine with calcium, magnesium, phosphorus, zinc, copper, iron, and inhibits their absorption by the body. To the above-mentioned, phytic acid inhibits the activity of enzymes that are designed to break down protein.

Therefore, you should think seriously before to go on a strict diet of oatmeal water, beans and raw nuts. As a result, you allow your body to demineralization. However, it is not necessary to panic. You just need to comply with the measure and learn how to cook whole grains. That is, previously to ferment.

Ruminants in the rumen produce a special enzyme - picazo, which promotes better assimilation of phytic acid. The human intestinal microflora also has this ability, but in much smaller amounts. The production of phytase can be activated in the grains that occurs during the long soak (12-24 hours).

But keep in mind that you cannot soak grits before cooking in hot water, because when temperatrue 80 degrees phytase will be destroyed in just 10 minutes, and the effect will be. the water should be komnenoi temperature or 40 degrees. Better the fermentation in an acidic environment, so you can add a few drops of lemon juice or malic acid.

Different grains are able to allocate different amounts of phytase to phytic acid destruction. So, oats, corn, millet, brown rice, even during prolonged soaking is not able to eliminate all the phytic acid. Therefore, you should at least eat these products. And cook them only after daily soaking.
