Yttrium(III) sulfate is an inorganic compound with the formula Y₂(SO₄)₃. The most common form is the anhydrate and octahydrate.

Reactions

Yttrium sulfate can form double salts such as MY(SO₄)₂ and M₃Y(SO₄)₃:

Y₂(SO₄)₃ + M₂SO₄ → 2 MY(SO₄)₂

(SO₄)₃ + 3 M₂SO₄ → 2 M₃Y(SO₄)₃ (M = alkali metals)

Synthesis

Yttrium(III) sulfate can be prepared using either corresponding oxide, hydroxide, or carbonate.

2 Y(OH)₃ + 3 H₂SO₄ → Y₂(SO₄)₃ + 6 H₂O
