용도
Iron(III) sulfate hydrate is a general use reagent qualified for use in plant research. It is redox active and my be used as a cell culture nutrient, in studies on iron metabolism or regulation and oxidative processes.
제조 방법
Anhydrous Fe2(SO4)3 is obtained as an almost white powder by
boiling anhydrous iron(II) sulphate with concentrated sulphuric acid or by careful heating
of the hydrated salt. Solutions of iron(III) sulphate prepared, for example, by oxidizing
solutions of iron(II) sulphate with nitric acid yield a series of hydrates upon crystallization;
the common hydrates have 12, 9 (the common, violet crystals), 6 and 3 molecules of water.
When thermally decomposed, iron (III) oxide and sulphur trioxide are formed :
Fe2(SO4)3→Fe2O3+3SO3
