hey there,
a) Na₂SO₃+BaCl₂ ----> BaSO₃+2NaCl
double displacement reaction takes place.
b) double displacement reaction.
c) BaSO₃+2HCl -----> BaCl₂+ H₂O+SO₂
as the product, barium chloride is water soluble, the white precipitate disappears.
hope it helps..

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
