Barium sulphate precipitate, 1 of 3. Barium sulphate (BaSO4) precipitate formed by adding barium chloride solution (BaCl2) drop by drop to zinc sulphate solution (ZnSO4). Both solutions are 0.5 M concentration. The reaction is ZnSO4 + BaCl2 -> BaSO4 + ZnCl2. This is an example of a double replacement reaction.
