Washing soda

The chemical name of washing soda is sodium carbonate decahydrate, and its chemical formula is Na2CO3.10H2O. So washing soda is hydrated salt of sodium carbonate containing 10 molecules of water of crystallization. But the anhydrous sodium carbonate which doesn’t have...

Hydrated Salts

The salts which contain water molecules are known as hydrated salts. For example the crystals of copper sulphate contain five molecules of water called water of crystallization. So the formula of hydrated salt of copper sulphate is CuSO4.5H2O. Water of Crystallization...

Geothermal Energy

In those areas of the earth where the level of volcanic activities is quite high, the rocks present in the earth are usually very hot. This heat energy of rocks present in the earth is called geothermal energy and can be used to produce electricity. To produce...

Ocean Thermal Energy

Ocean Thermal Energy Different layers of ocean have different temperature. Usually, the water at the surface of oceans is hot due to sunlight. While the water present in the deeper layers of oceans is cold. The difference in temperature of hot water present at the...
