延伸阅读
专一性 也称专属性。在分析化学中,当一个试剂只与一种离子或物质发生反应,而不与其他离子或物质起相同反应时,则该试剂可称专一性试剂,该反应称专属性反应。在大多数情况下,一种试剂往往可以与许多种离子或物质起作用。例如,铬酸钾不仅能与Pb2+作用,而且还能与Ba2+或Sr2+作用,并且都生成黄色沉淀。因此,铬酸钾不能被认为是Pb2+的专一性试剂。在实际工作中,专一性试剂和专属性反应是十分稀少的。例如 NH嬃与氢氧化钠作用,可以生成具有特殊性质的氨(有气味并能使红色石蕊试纸变蓝),因此,通常认为这是检出NH嬃的专属性反应。但是严格地说,它也不是专属性反应,因为CN-在热的氢氧化钠溶液中也会放出氨: CN-+2H2O→HCOO-+NH3↑如果在试液中加入少量二氯化汞,与CN-1结合,才能使反应(1)成为检验NH嬃的专属性反应。
