Chemical Properties
YELLOW-GREEN CRYSTALLINE POWDER
Uses
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.
Uses
Iron(III) sulfate is also used in pigments, pickling baths for aluminum and steel. It acts as a mordant in dyeing, as a coagulant for industrial wastes. In the medical field, it is used as an astringent and styptic. It is involved in the preparation of aromatic esters from the corresponding acids and alcohols. Further, it is employed in the oxidation of pyrite.
Uses
Iron(III) sulphate finds uses as a mordant and in the preparation of iron(III)
alum and Prussian blue.
Preparation
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
Definition
ChEBI: Iron(3+) sulfate hydrate is a hydrate that is the monohydrate form of iron(3+) sulfate. It has a role as a mordant, a catalyst and an astringent. It contains an iron(3+) sulfate.
