Thalloius bromide, TlBr

Thalloius bromide, TlBr, is prepared like the corresponding chloride. It is a pale yellow solid of density 7.54, and its compressibility coefficient is 5.2×10^-6 per atmosphere. It crystallises in the isometric system in cubes, melts to a brownish-yellow liquid at 450°, and boils at 800° to 814°. The bromide is stable at high temperatures.

The solubility of thallous bromide in water, in grams per 100 grams of water, is as follows: -

Temperature, °C.	18°	20°	25°	68.5°
Grams of TlBr	0.042	0.048	0.057	0.247

The specific conductivity of the saturated aqueous solution is 192×10^-6 reciprocal ohms per cm. cube at 18°.
