Thallium(I) nitrate, also known as thallous nitrate, is a thallium compound with the formula Tl NO₃. It is a colorless and highly toxic salt.

Preparation

Thallium(I) nitrate can be produced by reacting thallium(I) iodide with nitric acid.^[1]

However, the production is simpler starting from the metal, its hydroxide or the carbonate: ^[2]

TlOH + HNO₃ → TlNO₃ + H₂O

Tl₂CO₃ + 2 HNO₃ → 2 TlNO₃ + CO₂ + H₂O

Toxicity

Thallium(I) nitrate is extremely toxic, like many other thallium compounds. It is highly toxic by ingestion but can also be absorbed through skin due to its solubility in water.^[3]
