Properties

Solubility of rubidium nitrate in water

Rubidium nitrate is a white crystalline powder that is highly soluble in water and very slightly soluble in acetone. In a flame test, RbNO3 gives a mauve/light purple colour.

Uses

Rubidium compounds have very few applications.[1] 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 is rarely used in fireworks to produce a red-violet colour.

Production

RbNO3 can be prepared either by dissolving rubidium metal, its hydroxide or carbonate in nitric acid.

RbOH + HNO3 → RbNO3 + H2O
2 Rb + 2 HNO3 → 2 RbNO3 + H2
