Question

Give two examples of hydrated salts which are white in colour. Also write their chemical formula.

Answer 1

Magnesium sulphate(MgSO4) Sodium Carbonate (Na2CO3)

Answer 2

Answer: The two examples are washing soda and gypsum.

Explanation:

Washing soda is the common name for the compound sodium carbonate decahydrate. Its chemical formula is $Na_2CO_3.10H_2O$. It is used for washing purposes. It is white in color.

Gypsum is the common name for the compound calcium sulfate bihydrate. The chemical formula for this compound is $CaSO_4.2H_2O$. It is white in color. When it is heated, it leads to the formation of Plaster of Paris, generally known as POP.

Hence, the two examples are washing soda and gypsum.
