What happens when aqueous solutions of Sodium sulphate and Barium chloride are mixed? Give a balanced equation for the reaction with state symbols. Name and define the type of chemical reaction involved in the above change.

When an aqueous solution of sodium sulphate is made to react with barium chloride, a white colour precipitate of barium sulphate is formed. The reaction is as follows:

Na2SO4 + BaCl2→ 2NaCl + BaSO4


White


Ppt.


This reaction is a type of double displacement reaction which comes under the subtype of precipitation reaction.


Double Displacement Reaction is a type of chemical reaction in which anions and cations of the reacting compounds exchange their positions to form different compounds.


The precipitation reaction is a type of reaction in which one of the reactants is solvent, and one of the products formed is insoluble in the solvent.
