Indium(III) nitrate

Properties Indium nitrate forms colourless, deliquescent needle shaped crystals. one-third of its water of crystalization is decomposed at 100° and it becomes anhydrous when dessicated with concentrated sulphuric acid. It forms a double nitrate 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. 

 indium nitrate crystallises from the nitric acid solution due to its lower soubility in nitric acid due to the coming ion effect.
