C••A. A用硝酸银TS制成的氯化物溶液产生白色的乳白色沉淀，不溶于硝酸，但可溶于稍过量的6 N氢氧化铵。••B. B在测试对上述测试无反应的胺（包括生物碱）盐酸盐时，除非另有说明，否则将1滴稀硝酸和0.5 mL硝酸银TS添加到所检查物质的溶液中。专论中，每2 mL含约2 mg氯离子：形成白色凝结沉淀。立即离心混合物，并倾析上清液层。用三份1 mL的硝酸溶液（1：100）洗涤沉淀物，并弃去洗涤液。将氨水TS滴加到该沉淀物中。它容易溶解。•• C。

C = A.A 使用硝酸银 TS，氯化物溶液产生不溶于硝酸但可溶于 6 N 氢氧化铵的白色凝乳沉淀物。• B. B 在测试对上述测试没有反应的胺（包括生物碱）盐酸盐时，在2 mL中加入1滴稀释硝酸和0.5 mL硝酸银TS溶液，除非本专著另有说明，否则在2mL中加入约2毫克氯化物离子：形成白色、凝乳沉淀物。毫不拖延地将混合物离心，并倒入上一层。用三个 1 mL 的硝酸溶液 （1：100） 清洗沉淀物，然后丢弃洗涤液。将氨 TS 滴到此沉淀物中。它很容易溶解。• C. C 当专著规定一篇文章响应干氯化物的测试时，将固体与同等重量的二氧化锰混合测试，用硫酸滋润，然后轻轻加热混合物：氯，通过用湿润淀粉碘纸生产蓝色来识别。

C •• A. A With silver nitrate TS, solutions of chlorides yield a white, curdy precipitate that is insoluble in nitric acid but is soluble in a slight excess of 6 N ammonium hydroxide. •• B. B When testing amine (including alkaloidal) hydrochlorides that do not respond to the above test, add 1 drop of diluted nitric acid and 0.5 mL of silver nitrate TS to a solution of the substance being examined containing, unless otherwise directed in the monograph, about 2 mg of chloride ion in 2 mL: a white, curdy precipitate is formed. Centrifuge the mixture without delay, and decant the supernatant layer. Wash the precipitate with three 1- mL portions of nitric acid solution (1:100), and discard the washings. Add ammonia TS dropwise to this precipitate. It dissolves readily. •• C. C When a monograph specifies that an article responds to the test for dry chlorides, mix the solid to be tested with an equal weight of manganese dioxide, moisten with sulfuric acid, and gently heat the mixture: chlorine, which is recognizable by the production of a blue color with moistened starch iodide paper, is evolved.<br>
