Solubility Rules and Identifying a Precipitate

Barium chloride and potassium sulfate are both ionic compounds. We would expect them to undergo a double displacement reaction with each other. BaCl 2 + K 2 SO 4 BaSO 4 + 2 KCl By examining the solubility rules we see that, while most sulfates are soluble, barium sulfate is not. Because it is insoluble in water we know that it is the precipitate.
