LITHIUM NITRATE LiNO3

Properties of lithium nitrate:

White, very hygroscopic, melts without decomposition, decomposes on further heating. It is readily soluble in water (without hydrolysis). Oxidizing agent during sintering. In solution recovered only by atomic hydrogen.


Obtaining Lithium nitrate LiNO3:

3 Li + 4 HNO3 (ddiluted) = 3 LiNO3 + NO ↑ + 2H2O.

LiF + HNO3 (conc.) = LiNO3 + HF ↑.

Li2S + 4 HNO3 (conc.) = 2 LiNO3 + 2NO2 ↑ + S ↓ + 2H2O


Reactions with Lithium nitrate LiNO3:

4 LiNO3 = 2 Li2O + 4 NO2 + O2 (475—650° C).

LiNO3-3H2O = LiNO3 + 3 H2O (200° C, vacuum).

LiNO3 (diluted) + 4H2O = [Li(H2O)4]+ + NO3- ↑ (pH 7).

LiNO3 + 2 H0 (Zn, conc. HCl) = LiNO2 + H2O.

LiNO3 + Pb = LiNO2 + PbO (400° C)
