Rubidium sulfate is a sulfate of rubidium with the chemical formula Rb2SO4.

Reactions

Rubidium sulfate reacts with yttrium(III) sulfate forming a double salt:[2]

Y2(SO4)3 + Rb2SO4 → Rb3[Y(SO4)3]

Rubidium sulfate reacts with sulfuric acid forming rubidium hydrogen sulfate, the acid sulfate:[3]

Rb2SO4 + H2SO4 → 2 RbHSO4
