Answer:
When a solution of sodium sulphate is added to a solution of barium chloride, a white precipitate of barium sulphate is seen to be formed immediately.
This precipitate is insoluble in dilute hydrochloric acid( dil.HCl).
This is an example of precipitation reaction as a distinct white precipitate is formed.
The equation of the above mentioned reaction is given as follows:
Na2SO4(aq)+BaCl2(aq)---> BaSO4(s)+2NaCl(aq)
