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 optics, in pyrotechnic compositions as a pyrotechnic colorant and as an oxidizer, e.g. in decoys and illumination flares although it is rarely used in fireworks to produce a red-violet colour. 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.

Production

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

RbOH + HNO3 → RbNO3 + H2O
Rb2CO3 + 2 HNO3 → 2 RbNO3 + CO2 + H2O
2 Rb + 2 HNO3 → 2 RbNO3 + H2
