washing soda.- Na2 CO3

synthesis

1. The precipitates of sodium bicarbonate are separated by the process of filtration.
2. It is then heated and dried.
3. washing soda contains 10 molecules of water of crystallization.
4. so, anhydrous sodium carbonate is mixed with water to form washing soda.

equation

2NaHCO3 --------> Na2CO3 + H2O +CO2..
