TlCl3 - THALLIUM (III) CHLORIDE

Properties of thallium (III) chloride:

White, decomposes when heated. In the acidified concentrated solution is stable, in a dilute solution is completely decomposed. It reacts with hydrochloric acid and alkalis. Oxidizer.


Molar mass g/mol 310.74
Density g/cm3 3.03
Melting point °C 155

Methods for preparation of thallium (III) chloride:

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


Chemical reactions with thallium (III) chloride:

2TlCl3 = Tl[Tl(III)Cl4] + Cl2 (above 40° C).

TlCl3 = TlCl + Cl2 (above 150° C).

TlCl3 • 4H2O = TlCl3 + 4H2 (normal temp., vacuum, above H2SO4).

TlCl3(conc.) + 3H2O(cold) = [Tl(H2O)3Cl3] (in diluted HCl),

2[Tl(H2O)3Cl3] = [Tl(H2O)4Cl2](+) + [TlCl4](-) + 2H2O.

2TlCl3(diluted) + 3H2O(hot) = Tl2O3↓ + 6HCl.

TlCl3 + HCl(conc.) = H[TlCl4].

2TlCl3 + 6NaOH(diluted) = Tl2O3↓ + 6NaCl + 3H2O.

2TlCl3 + 3H2S = Tl2S↓ + 2S↓ + 6HCl.

TlCl3 + 3KCl(conc.) = K3[TlCl6].

2TlCl3 + 3CsCl = Cs3[Tl2Cl9].

TlCl3(conc.) + 2Tl(powder) = 3TlCl↓.
