Washing soda is sodium carbonate containing 10 molecules of water of crystallisation.It is called as sodium carbonate decahydrate.
The formula of washing soda is
Na2CO3.10H2O
Uses
1)It is used to remove permanent hardness of water.
2)It is used in the manufacture of glass,soap,paper.
3)It is used for washing clothes.
4)It is used in the manufacture of borax.
preparation:
1. 2NH3 +H2O + CO2 gives (NH4)2CO3
2. (NH4)2CO3 + H2O + CO2 gives 2NH4HCO3
3. NH4HCO3 + NaCl gives NaHCO3 + NH4Cl
Sodium carbonate (also known as washing soda, soda ash and soda crystals, and in the monohydrate form as crystal carbonate), Na2CO3, is the water-soluble sodium salt of carbonic acid. It most commonly occurs as a crystalline decahydrate, which readily effloresces to form a white powder, the monohydrate.
