What happens in the conical flask when two solutions - barium chloride and sodium sulphate are mixed together?

When solutions of barium chloride and sodium sulphate are mixed together, then an insoluble precipitate of barium sulphate and solution of sodium chloride is obtained. Hence, this reaction is a precipitation (a kind of double displacement reaction) reaction. The chemical equation for reaction between barium chloride and sodium sulphate is represented as follows

BaCl2 + Na2SO4 → BaSO4 + 2NaCl
