following reactions.
(i) Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium Chloride.

 

Answer

(i)

 

BaCl 2 (aq) + Na 2 SO 4 (aq) ⇒ BaSO 4 (s) + 2NaCl (aq)

 

Note that the reaction does not happen if Barium Chloride and Sodium Sulphate are solid. 

 

This an example of Double Displacement reaction.
