使用Silver cyanide is used in silver-plating.
一般的な説明A white to gray odorless tasteless powder that darkens on exposure to light. Insoluble in water. Toxic by skin absorption through open wounds, ingestion and inhalation of dust. Toxic oxides of nitrogen are produced in fires.
純化方法It is a POISONOUS white or grayish white powder. Stir it thoroughly with H2O, filter, wash well with EtOH and dry it in air in the dark. It is very insoluble in H2O (0.000023g in 100mL H2O) but is soluble in HCN or aqueous KCN to form the soluble Ag(CN) 22 complex.
