Description
Grayish-white powder formed by adding Sulfuric acid to Ferric hydroxide. Ferric sulfate is very Hygroscopic. It is used as a mordant in textile dyeing and as a component in iron gall inks. Ferric sulfate is also used in water purification systems. Ferric sulfate occurs naturally in minerals with varying states of hydration, including lausenite [Fe2(SO4)3-6H2O], Kornelite [Fe2(SO4)3-7H2O], Coquimbite [Fe2(SO4)3-9H2O], and Quenstedtite [Fe2(SO4)3-10H2O].
