王水
aqua regia
    浓硝酸和浓盐酸以1∶3体积比配制而成的混合溶液。其中硝酸和盐酸发生以下反应:
   HNO3+3HCl!!!W0302_1NOCl+Cl2+2H2O产生的氯气和氯化亚硝酰(NOCl)及硝酸都是强氧化剂,溶液中还存在着Cl-  ,能与金、铂形成稳定的络离子[AuCl4] -、[PtCl6] 2-,因此王水能溶解不与浓硝酸、浓硫酸、浓盐酸作用的金和铂:
   Au+HNO3+4HCl!!!W0302_2HAuCl4+NO+2H2O
   3Pt+4HNO3+18HCl!!!W0302_33H2[PtCl6]+4NO+8H2O
   王水的性质不稳定,宜在使用前配制。
