If 500 mL of a solution containing 1.00 g of barium nitrate (199.33 g/mol) is combined with 500 mL of a solution containing 1.00 g of sodium sulfate (142.03 g/mol), will there be a precipitate? (Barium sulfate has a K_sp value of 9.1 * 10^-11.)

Question

Quizplus · Accepted Answer

Barium sulfate (BaSO4) will precipitate because when solutions of barium nitrate and sodium sulfate are mixed, barium sulfate, which is insoluble in water, forms as a solid precipitate. This is due to the low solubility product (Ksp) of barium sulfate, indicating it is not soluble in water and will precipitate out of solution.
