What is the chemical name of washing soda?

Answer and explanation

Correct answer: Sodium carbonate decahydrate

Washing soda is sodium carbonate decahydrate, written as Na₂CO₃·10H₂O. The ten water molecules are called water of crystallisation, so option C is correct. Sodium hydrogen carbonate, NaHCO₃, is baking soda; sodium chloride is common salt; and calcium sulphate hemihydrate is plaster of Paris. These distinctions are based on the chemical composition and names of the salts.
