TlNO3- THALLIUM (I) NITRATE

Properties of thallium (I) nitrate:

White, melts without decomposition, upon further heating decomposes. It is readily soluble in water (hydrolysis isn't present), the solubility increases strongly with increasing temperature. Does not form crystalline hydrates. Reducing agent. Participates in exchange reactions.


Molar mass g/mol 266.39
Density g/cm3 5.556
Melting point °C 206.5

Methods for preparation of thallium (I) nitrate:

3Tl + 4HNO3(diluted, hot) = 3TlNO3 + NO↑ + 2H2O,

TlOH + HNO3(diluted) = TlNO3 + H2O.

2TlOH(diluted) + Zn(NO3)2 = Zn(OH)2↓ + 2TlNO3,


Chemical reactions with thallium (I) nitrate:

4TlNO3 = Tl2O3 + Tl2O + 4NO2 (250-350° C),

4TlNO3 = 2Tl2O + 4NO2 + O2 (above 500° C).

TlNO3(diluted) + (n)H2O = [Tl(H2O)(n)](+) + NO3(-) (pH = 7).

TlNO3 + 4HNO3(conc.)= Tl(NO3)3 + 2NO2 + 2H2O.

TlNO3 + NaCl = TlCl↓ + NaNO3.

2TlNO3 + H2S = Tl2S↓ + 2HNO3.

3TlNO3 + Na3PO4 = Tl3PO4↓ + 3NaNO3.

2TlNO3 + K2CrO4 = Tl2CrO4↓ + 2KNO3,

2TlNO3 + K2Cr2O7 = Tl2Cr2O7↓ + 2KNO3.

5TlNO3 + 16HNO3 + 2KMnO4 = 5Tl(NO3)3 + 2Mn(NO3)2 + 8H2O + 2KNO3.
