Sodium carbonate manufacturing process, solvay process

Sodium carbonate is a white crystalline solid which exists as a decahydrate (Na 2 CO 3 .10H 2 O). This is called washing soda. When decahydrate gets heat, it looses the water of crystallization to form monohydrate ( Na 2 CO 3 .H 2 O). Above 373K, the monohydrate becomes completely anhydrous and changes to a white powder called soda ash.
