Chemical compound

Lanthanum(III) nitrate is any inorganic compound with the chemical formula La(NO3)3·xH2O. It is used in the extraction and purification of lanthanum from its ores.

The compound decomposes at 499°C to lanthanum oxide, nitric oxide and oxygen.

Preparation

Lanthanum nitrate is prepared by reacting lanthanum oxide with nitric acid which creates lanthanum(III) nitrate and water.

La2O3 + 6 HNO3 → 2 La(NO3)3 + 3 H2O
