Infobox references

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.[5]

The compound decomposes at 499°C to lanthanum oxide, nitric oxide and oxygen.[3]

Preparation[edit]

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
