Rubidium nitrate is a chemical compound of RbNO₃. It is a stable nitrate of rubidium. Rubidium nitrate is an oxidant and should be kept away from combustible material.

Properties

Solubility of Rubidium nitrate in water

Rubidium nitrate is a white crystalline powder highly soluble in water and hardly soluble in acetone. When a flame test is performed, RbNO₃ gives a mauve/light purple colour.

Uses

Like caesium nitrate, it is used in infrared radiation producing pyrotechnic compositions as a colorant and an oxidizer, e.g. in decoys and illumination flares. It is also used as a raw material for preparation of other rubidium compounds and rubidium metal, for manufacture of catalysts and in scintillation counters. It finds uncommon use in fireworks to produce a red-violet color.

Production

RbNO₃ may be produced by a reaction between rubidium hydroxide or elemental rubidium and nitric acid:
