CESIUM SULFATE Cs2SO4

Properties of cesium sulfate Cs2SO4:

White, volatile, melts without decomposition. Readily soluble in water (without hydrolysis). Does not form crystalline hydrates. Participates in exchange reactions.

 

Obtaining cesium sulfate Cs2SO4:

8 Cs + 6H2SO4 (diluted, cold) = 4 Cs2SO4 + SO2 + S↓ + 6 H2O (impurity H2S).

2 CsOH + H2SO4 (diluted) = Cs2SO4 + 2H2O.

Cs2S (solid) + 2O2 = Cs2SO4 (t> 500° C).

 

Сhemical reactions with cesium sulfate Cs2SO4:

Cs2SO4 (diluted) + 12 H2O = 2[Cs(H2O)6]+ + SO42- (pH 7).

Cs2SO4 (solid) + H2SO4 (conc.) = 2 CsHSO4.

Cs2SO4 + ВаE2 = BaSO4↓ + 2 CsE (E = Cl-, OH-).

Cs2SO4 + Al2(SO4)3 + 24 H2O = 2{CsAl(SO4)2·12H2O}↓ (alum).
