硝酸(nitric acid)分子式hno?,是一种有强氧化性、强腐蚀性的无机酸,酸酐为五氧化二氮。硝酸的酸性较硫酸和盐酸小(pka=-1.3),易溶于水,在水中完全电离,常温下其稀溶液无色透明,浓溶液显棕色。硝酸不稳定,易见光分解,应在棕色瓶中于阴暗处避光保存。硝酸在工业上主要以氨氧化法生产,用以制造化肥、硝酸盐等,在有机化学中,浓硝酸与浓硫酸的混合液是重要的硝化试剂。 nitric acid( nitric acid ) formula hno? is a strong oxidation, strong is the acid acid 酐 无机 for five of the nitrogen. nitric acid are relatively small and sulphuric acid-which hydrochloric ( pka as -1.3 ), aresoluble in water, in the water, electricity is completely under common temperature is colourless transparent and its solution is a strong solution brown. nitric acid, 易见光 down, on the brown of thebottle to keep away from the gloom. nitric acid in industry mainly ammonia production of law, to create such as chemical fertilizers, 硝酸盐 in 本公司供应无机酸的东莞硝酸,品质保证,欢迎洽谈。
