Question

What is observed when a solution of sodium sulphate is added to a solution of barium chloride taken in a test tube? Write equation for the chemical reaction involved and name the type of reaction in this case.

Answer 1

`BaCl_(2)(aq) + Na_(2)SO_(4) (aq) rarr BaSO_(4)(s) + 2NaCl(aq.)`
When a solution of sodium sulphate is added to a solution of barium chloride, then a white precipitate of barium sulphate is formed along with sodium chloride solution. Hence, this reaction is precipitation reaction.
