Lime gives a vdute turbidity on addition of saturated ammonium oxalate solution, and sulphates with barium chloride acidified with hydrochloric acid. A useful reagent for nitrites is metaphenylene diamine, 5 grams of which are dissolved in water, acidified with dilute sulphuric acid, and made up to one litre. It may be necessary to previously decolorise the solution with charcoal. If nitrites are present in the water to be tested, on addition of the diamine, a yellow colour is produced, either immediately or upon standing. Starch-iodide solution acidified with dilute sulphuric acid may also be used, the characteristic blue colour of the starch-iodine complex indicating nitrites, but this test is not altogether satisfactory.

Many metallic elements in their ionic forms react with negative counterions to produce stable precipitates. Silver ions form stable and highly insoluble salts with chloride, bromide, and iodide. Calcium precipitates quantitatively with oxalate and can be measured reproducibly at any of the three temperature-dependent plateaus as the oxalate, the carbonate, and the oxide. Barium precipitates quantitatively as the sulfate. The reactions often follow the same pattern ... [Pg.2030]
