Solution

When sodium sulphate and barium chloride are mixed together in their solid forms, no formation of products takes place. But when sodium sulphate and barium chloride are mixed together in their aqueous form, the formation of barium sulphate takes place. The formed product is white in color.
The chemical change is represented by:
\[\ce{Na2SO4 + BaCl2-> BaSO4 + 2NaCl}\]
