Zirconium(IV) sulfate is the name for a family of inorganic salts with the formula Zr(SO4)2(H2O)n where n = 0, 4, 5, 7. These species are related by the degree of hydration. They are white or colourless solids that are soluble in water.
Preparation and structure[edit]
Zirconium 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]
Uses[edit]
Zirconium sulfate is used in tanning white leather, as a catalyst support, to precipitate proteins and amino acids, and as a pigment stabilizer.
