LITHIUM CHLORIDE LiCl

Properties of lithium chloride LiCl:

White, deliquescent. Melts and boils without decomposition. Readily soluble in water (hydrolysis does not). Decomposed by concentrated acids. Participates in exchange reactions.

Obtaining lithium chloride LiCl:

2Li + 2 HCl (diluted) = 2LiCl + H2↑.

2Li + E2 = 2LiE (normal temp., E = F, Cl, Br; t> °C C, E = I).

LiH + HCl (diluted) = LiCl + H2↑ (normal temp.).

LiH + Cl2 = LiCl + HCl (400-450°C).

Li2O + 2HCl (diluted) = 2LiCl + H2O.

LiOH + HCl (diluted) = LiCl + H2O.

Li2CO3 + 2HCl (diluted) = 2LiCl + CO2↑ + H2O.

Li2SO4 + BaCl2 = BaSO4↓ + 2LiCl.


Reactions with lithium chloride LiCl:

LiCl-H2O = LiCl + H2O (t> 98°C).

LiCl (diluted) + 4 H2O = [Li(H2O)4]+ + Cl-.

2LiCl (solid) + H2SO4 (conc.) = Li2SO4 + 2 HCl↑ (boiling).

LiCl + LiHSO4 = Li2SO4 + HCl (450-500°C).

LiCl (conc.) + NH4F(conc.) = LiF↓ + NH4Cl.

LiCl (cold) + AgNO2(saturated) = LiNO2 + AgCl↓.

3LiCl (conc.) + K3PO4 = Li3PO4↓ + 3 KCl.

3LiCl (conc.) + Na2HPO4 + NaOH = Li3PO4↓ + H2O + 3 NaCl.

LiCl (conc.) + 4(NH3-H2O) (conc.) = [Li(NH3)4]Cl + 4 H2O.

2 LiCl (liquid) → Electrolysis → 2Li (on cathode) + Cl2↑(on anode).

2 LiCl + 2H2O → Electrolysis → 2LiOH + H2↑(on cathode + Cl2 (on anode).

2 LiCl (melt)(on Hg-cathode) → Electrolysis → 2Li(on cathode) + Cl2↑(on anode)

Hot peppers get their heat from a molecule called capsaicin. While the molecule acts as an irritant to mammals, including humans, birds lack the receptor responsible for the effect and are immune to the burning sensation from exposure.
