Question

On adding a drop of barium chloride solution to an aqueous solution of sodium sulphite, white precipitate is obtained. (A.) Write a balanced chemical equation of the reaction involved.(b.) What other name can be given to this precipation reaction?(c.) On adding dilute hydrochloric acid to the ​

Answer 1

Answer:

Barium sulphate precipitate can be formed

Explanation:

Bacl +Naso4 = baso4 +nacl

Answer 2

a)On adding a drop of Barium Chloride solution to an aqueous solution of sodium sulphite, white precipitate is obtained.This  white precipitate is a barium sulphite.

BaCl2 + Na2SO3------>BaSO3 + 2NaCl

b) This reaction is also a double displacement reaction.

c) On adding dilute hydrochloric acid to the reaction mixture, Barium Chloride ,Sulphur dioxide and water are formed. Since Barium  chloride is a soluble substance thus, white precipitate disappears.

BaSO3 + HCl --------> BaCl3 + SO2 + H2O
