Answer:

When a solution of sodium sulphate is added to a solution of barium chloride, a white precipitate of barium sulphate will be formed immediately. This precipitate is insoluble in dilute hydrochloric acid (dil.HCl) and also insoluble in water. This type of reaction is called precipitation reaction as the Baso4 precipitate thus formed is of white colour.

The equation of the above mentioned reaction is given as follows:

Na2SO4 (aq) + BaCl2(aq) -------> BaSO4(s) + 2NaCl(aq)

Since, barium sulphate is insoluble in water, so it will precipitate as a solid, where as the sodium chloride will remain in solution.

Answer:

when barium chloride reacts with sodium sulphate it forms and white precipitate in the bottom of the test tube this precipitate is white in colour and this reaction is known as precipitation reaction we can find out sodium sulphate using barium chloride
