Thallium (I) nitrate is a chemical compound from the group of thallium compounds and nitrates .

Extraction and presentation

Thallium (I) nitrate can be obtained by reacting thallium (I) iodide with nitric acid. However, it is easier to manufacture starting from the metal itself, its hydroxide or the carbonate:

${\displaystyle \mathrm {TlOH+HNO_{3}\longrightarrow \ TlNO_{3}+H_{2}O} }$

${\displaystyle \mathrm {Tl_{2}CO_{3}+2\ HNO_{3}\longrightarrow \ 2\ TlNO_{3}+CO_{2}} }$

properties

Thallium (I) nitrate is a moisture-sensitive, hygroscopic, white, odorless, oxidizing solid. It decomposes when heated, producing nitrous gases and thallium oxides. It is soluble in water, the solubility increasing extremely strongly when heated.

use

Thallium (I) nitrate is used for chemical production and analysis and as an additive in the production of fiber optic lenses .
