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[]

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[]

Zirconium sulfate is used in tanning white leather, as a catalyst support, to precipitate proteins and amino acids, and as a pigment stabilizer.
