These species are related by the degree of hydration. They are white or colourless solids that are soluble in water. Preparation and structureZirconium sulfate is prepared by the action of sulfuric acid on zirconium oxide: ZrO2 + 2 H2SO4 + H2O → Zr(SO4)2(H2O)x The anhydrous sulfate is also known. These compounds adopt complex structures featuring 7- and 8-coordinated Zr centres. Both water and sulfate serve as ligands.[2][3] UsesZirconium sulfate is used in tanning white leather, as a catalyst support, to precipitate proteins and amino acids, and as a pigment stabilizer.
