Expert Answer
The chemical name of washing soda is Sodium carbonate Decahydrate. The formula is Na2CO3.10H2O
It is obtained by heating baking soda followed by recrystallisation. During recrystallisation water molecules are added into the molecule of washing soda.
2NaHCO3.10H2O→ Na2CO3 + H2O + CO2
Na2CO3 + 10H2O → Na2CO3.10H2O
