Answer 1

Hello... ☺


The formula of washing soda =

Na2CO3.10H2O

Uses:-

1)It is used to remove permanent hardness of water.
 
2)It is used in the manufacture of glass,paper....

3)It is used for washing clothes.

preparation:-

1. 2NH3 ➕H2O ➕ CO2--------» (NH4)2CO3

2. (NH4)2CO3 ➕H2O ➕ CO2 ------»2NH4HCO3

3. NH4HCO3 ➕ NaCl -----» NaHCO3 ➕NH4Cl

thank you ☺

Answer 2

¤ The Chemical Name of Washing Soda is Hydrated Sodium Carbonate.

¤ Chemical Formula is Na2CO3.10H2O

Obtained by heating sodium hydrogen carbonate.
2NaHCO3-->Na2CO3+ H2O+CO2

. The re-crystallization of sodium carbonate produces washing soda.
Na2CO3+10H2O -->Na2CO3.10H2O

Uses of washing soda:
1.Sodium carbonate is used in glass, soap and paper industries
2.It is used in the manufacture of sodium compound such as borax
3.Sodium carbonate can be used as a cleaning agent for domestic purposes.
4. It is used for removing permanent hardness
