混酸也称混合酸(英文名称mixed acide),又名超强酸,比100%的硫酸还强的酸。是为了达到特定的目的,而将特定两种或两种以上的酸,按特定的比例,特定的混合方式混合而得到,用于特定的化学或工艺过程。一般是两种强酸的混合,很多时候混合后酸性或某种性能会增强。但不一定,例如硝酸和氢硫酸混合生成硫单质和二氧化氮,酸性可消失,但这种混合没有实际意义。硝酸和盐酸按一定比例混合的混酸,称为“王水”,是一种非常强的混酸,能溶解金、铂这样难溶的金属。几种常用的混酸和匹配的化工过程及产品举例如下:
... 氧化铁;铁红;锈氧红;Ferric oxide 氧化铁;三氧化二铁;铁红;ferric oxide 混合酸;混酸;mixed acid;nitrating acid ...
