Dissolve 1 25 g In 10 ml water, add 2 ml oi nitric acid and sufficient water to produce 50 ml. the resulting solution complles with the limit test for chlorides, Appendix 3. 10 (200 ppm).Sulphate. Dissolve 0 375 g in 10 ml oi water, add 2 ml o hydrochloric acid and sufficient water to produce 15 ml. the resulting solution complies with the limit test for sulphates Appendix 3 15 (400 ppm).Reducing sugars Dissolve 1 g in 10 ml of water, add 5 m of potassium cupri-tartrale solution and boil, not more that a slight brick-red precipitate is produced Loss on drying. Not more than 30%. determined on 05 g by drying in an oven at 120° for 4 hours.
