Solution
When a solution of barium chloride is added to a solution of sodium sulphate, an insoluble substance Barium sulphate is formed which is insoluble in water. Therefore it is also called precipitation reaction
In double displacement reaction the aqueous ionic solutions of two salts react by exchanging their ions/radicals to form two new compounds so this reaction is also called double replacement reaction
