Chlorophytum moisturizes the air and clears it from harmful substances, poisons as well as microorganisms and bacteria. This is one of the most unpretentious of indoor plants complement the decor of any apartment and benefit of its residents. Four adults flower purify the air in the room 10 square meters on 70-80%.
Aloe is widely distributed in folk medicine for its curative properties. In addition, it reduces the level of harmful substances, including those emitted from furniture, particle Board, 90%. Night, this plant absorbs carbon dioxide and releases oxygen.
Kalanchoe is an adaptable houseplant. Only water and bright sunlight necessary for its growth and flowering. The aroma of this flower helps to relieve depression, but also enriches the air with oxygen day and night.
Begonia, especially the Royal, is the symbol of material prosperity. Indoors begonia neutralize harmful substances and germs. Its flavor improves mood, so the bedroom of older people is perfect for this flower.
Geranium improves mood, relieves internal stress, relieves depression, but also enriches air with oxygen and ozone. Thanks to these valuable properties, this flower is widely distributed in the apartments and office premises.
Sansevieriya or Teschin language is ideal for bedrooms and any other enclosed spaces. A few such plants in the room provide clean and oxygenated air day and night.
Cactus is ideal for rooms in which there are electromagnetic devices. The longer needles of a cactus, the more effectively it neutralizes the gas to absorb radiation. Cactus is a hardy plant, but for best growth and efficiency it needs more light.
Laurel is an ideal plant for children's bedroom, in which relieves insomnia and promotes healthy sleep. This flower relieves headaches and improves mood.
Lavender has always been a symbol of calm and healthy sleep, but it is not widespread in the form of potted plants.
Advice 2: How to release oxygen from water
Pure oxygen in large quantities is used in medicine, industry and other fields. For these purposes it is obtained from air by liquefaction of the latter. In the laboratory the gas can be obtained from the oxygenostergade compounds, including water.
You will need
- - clean the tubes;
- - DC generator.
Before beginning the experiment, repeat safety. Strictly observe the rules of work with electrical appliances. Also, remember that the produced gases are flammable and explosive, therefore, require careful handling.
Repeat the concept of electrolysis. Remember that the cathode (negatively charged electrode) will undergo the process of electrochemical reduction. Consequently, there will be collected hydrogen. And at the anode (positively charged electrode) - the process of electrochemical oxidation. There would be atoms of oxygen. Write down the reaction equation: 2H2O → 2H2+О2Катод: 2H + 2e = H2 │2Анод: 2O – 4e = O2 │1
Prepare two electrodes. You can get them from copper or iron plates with a length of 10 cm and a width of about 2 cm Attach to them conductors of electric current.
Then in the pot, pour water and lower back electrodes. As a vessel for electrolysis use a deep mold or glass thick-walled, extending up.
Then take two clean test tubes and pour back the water. Close them with corks. Later open these vessels under water in electrolyzer and immediately put on the electrodes. Do this carefully so the water from the test tubes are not spilled. This is necessary in order to prevent air and in the process of electrolysis were clean gases.
Connect the DC generator. Turn it on when you know it's prepared correctly. Under the action of electric current on the electrodes will begin bubbling gases. Gradually the oxygen and hydrogen will fill the tubes, displacing the water.
Keep in mind that according to the reaction equation of hydrogen will be collected two times more oxygen.
The electrodes can use thick nails, suitable in size to the vessels.
