LITHIUM SULFATE Li2SO4

Properties of lithium sulfate:

White, melts without decomposition. It is readily soluble in water (hydrolysis does not). Participates in exchange reactions.

Obtaining lithium sulfate:

2 LiH + 2 SO2 = Li2SO4 + H2S (200° C).

Li2S + 2 O2 = Li2SO4 (t> 300° C)

Reactions with lithium sulfate:

Li2SO4-H2O = Li2SO4 + H2O (130—500° C).

Li2SO4 (diluted) + 8H2O = 2[Li(H2O)4]+ + SO42- (pH7).

Li2SO4 + H2SO4 (conc.) = 2 LiHSO4.

Li2SO4 (conc.) + Na2CO3 = Li2CO3 ↓ +Na2SO4.

Li2SO4 + BaCl2 = BaSO4 ↓ + 2LiCl.

Li2SO4 + Ba(OH)2 = BaSO4 ↓ + 2 LiOH.

Li2SO4 + Ba(N3)2 = 2 LiN3 + BaSO4 ↓.

Li2SO4 + 4 C (coke) = Li2S + 4 CO (800—900° C).

Li2SO4 + 4 H2 = Li2S + 4 H2O (600—700° C).
