TlCl - THALLIUM (I) CHLORIDE

Properties of thallium (I) chloride:

White, volatile at moderate heating, light-sensitive. Poorly soluble in water. It does not form crystalline hydrates. It is reacted with sulfuric acid, nitric acid, and oxidized with chlorine. It is recovering by hydrogen.


Molar mass g/mol 239.84
Density g/cm3 7.0
Melting point °C 431
Boiling point °C 818

Methods for preparation of thallium (I) chloride:

2Tl + Cl2 = 2TlCl (normal temp.),

Tl2SO4 + 2HCl(conc.) = 2TlCl↓ + H2SO4.

TlNO3 + NaCl = TlCl↓ + NaNO3.

Tl2CO3 + 2HCl(diluted) = 2TlCl↓ + H2O + CO2↑.


Chemical reactions with thallium (I) chloride:

2TlCl = TlCl(1-x) + 0.5(x)Cl2 (in the light, normal temp.).

TlCl(solid) + H2SO4(conc.) = TlHSO4(р) + HCl↑ (20-40° C).

TlCl + 5HNO3(conc.) = Tl(NO3)3 + 2NO2↑ + HCl + 2H2O.

2TlCl + H2 = 2Tl + 2HCl (650-750° C).

3TlCl + 6HCl(conc.) + 8KCl + KClO3 = 3K3[TlCl6] + 3H2O.

TlCl(suspension) + Cl2 = TlCl3 (normal temp.).

The only elements that are liquid at room temperature are bromine and mercury. However, you can melt gallium by holding a lump in the warmth of your hand.
