Twenty-five grams (0.1 mol) of copper(II) sulfate 5-hydrate is placed in a 400-ml. beaker and dissolved in 150 ml. of water. A second solution is prepared by placing 36.5 g. (0.22 mol) of potassium iodide and 28.0 g. (slightly more than 0.11 mol) of sodium thiosulfate 5-hydrate in a 100-ml. volumetric flask, adding water to the mark, and shaking thoroughly, f The second solution is added to the first from a buret with continuous, rapid stirring until no further precipitation occurs (90.9 ml. is theoretically required).

Addition of the potassium iodide-sodium thiosulfate solution from a buret is unnecessary because the product is not appreciably soluble in moderate excesses of potassium iodide. The second and third sentences in the Procedure should be replaced by the following A second solution is prepared by dissolving 16.6 g. (0.10 mole) of potassium iodide and 25 g. of sodium thiosulfate 5-hydrate in 100 ml. of water. The second solution is added to the first with continuous rapid stirring. ... [Pg.244]
