Chemical formula of washing soda is - (1) Na2SO4.10H2O (2) NaHCO3 (3) Na2CO3.10H2O (4) Ca(OH)2

1 Answer

Answer :

(3) Na2CO3.10H2O Explanation: Washing Soda is essentially Sodium Carbonate, a sodium salt of carbonic acid (soluble in water). The molecular formula of washing soda is Na2CO3.10H2O. It is used as an agent to soften hard water. It reacts with the calcium and magnesium bonds present in the water, enabling the detergent to work.
