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 precipitation reaction?

(c) On adding dilute hydrochloric acid to the reaction mixture, white precipitate disappears. Why?

Answers (1)

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

BaCl_2 + Na_2SO_3\rightarrow BaSO_3 + 2NaCl

(b) In this case precipitation reaction is a double displacement.

(c) When we add dilute HCl to this reaction mixture Barium chloride, Sulphur dioxide and water are formed. Barium chloride is a soluble substance which will make the white precipitate disappear.

BaSO_3 + 2HCl \rightarrow BaCl_2 + SO_2 + H_2O.
