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
