What happens when crystals of washing soda are exposed to air?

Text Solution

Verified by Experts

Sodium carbonate, commonly known as washing soda crystallises as decahydrate which is white in colour. Upon heating, it loses the water of crystallisation to form monohydrate due to efflorescence. Above 373 K, the monohydrate becomes completely anhydrous and changes to a white powder called soda ash.
