Indium(III) nitrate is a nitrate salt of indium.

Properties

Indium nitrate forms colourless, deliquescent needle shaped crystals. One-third of its water of crystallization is decomposed at 100° and it becomes anhydrous when desiccated with concentrated sulfuric acid. It forms a double salt with ammonium nitrate.

Production

Indium metal reacts with nitric acid and reduces the acid to ammonia gas, due to the reducing nature of indium metal. A more pure product can be obtained by reacting indium (III) hydroxide with nitric acid it dissolves slowly in dilute nitric acid and more rapidly in concentrated nitric acid. The indium nitrate crystallizes from the nitric acid solution due to its lower solubility in nitric acid due to the common ion effect.^[1]
