[[File:Síran železitý.JPG|thumb|Iron(III) sulfate]] '''Iron(III) sulfate''', also known as '''ferric sulfate''', is a [[chemical compound]]. It has [[iron]] in its +3 [[oxidation state]] and [[sulfate]] [[ion]]s. ==Properties== It is a white to yellow to pale purple [[crystalline]] solid. It is a weak [[oxidizing agent]]. It dissolves in water to make an [[acid]]ic [[solution]]. ==Occurrence== It is found as a mixed iron(III) [[aluminium sulfate]]. This is the [[anhydrous]] form. Several [[hydration|hydrated]] forms are found, too. Much more iron(III) sulfate is found in Mars. One of the [[rover]]s that travel on Mars got stuck in a pit of iron(III) sulfate and could not get out. ==Preparation== It is made by mixing [[sulfuric acid]], [[iron(II) sulfate]], and an [[oxidizing agent]] like [[nitric acid]] or [[hydrogen peroxide]] together. It is made when [[iron(III) oxide]] reacts with [[sulfuric acid]]. It is also made when iron(II) sulfate is [[oxidation|oxidized]] by exposure to oxygen. ==Uses== It is used as a [[mordant]] in [[dyeing]]. It is also used to [[coagulation|coagulate]] waste to remove the toxic parts. It is also used in baths to clean metals. It can be used as a pigment. It is used as an [[astringent]] in [[medicine]].
