What happen when an aqueous solution of sodium sulphate reacts with an aqueous solution of barium chloride? State the physical conditions of reactants in which the reaction between them will not take place. Write the balanced chemical equation for the reaction and name the type of reaction.


When the barium chloride solution is added to sodium sulphate solution, a white precipitate of barium sulphate is formed along with sodium chloride solution.

The reaction will not take place if the reactants are in solid-phase i.e.Solid sodium sulphate and Solid barium chloride.

The balanced chemical equation for the reaction is given below:
$BaCl_{2}( aq) \ +\ Na_{2} SO_{4}( aq) \ \rightarrow BaSO_{4}( s) \ +\ 2NaCl( aq)$
It is a Double displacement reaction as the ions are exchanged in the products.
