5.0 cm3 of 0.5 mol dm-3 sodium sulphate solution was placed into eight different test tubes of the same size. Different volumes of 0.5 mol dm-3 Z chloride solution was added to each test tube. The mixture was shaken, and the height of the precipitate formed was measured after one hour. The result is shown in Diagram.
