Rubidium nitrate is an inorganic compound with the formula RbNO3.
Rubidium nitrate is an oxidizer and mixtures with combustible materials are flammable.
Rubidium nitrate will decompose above 300-310 °C to yield rubidium nitrite and oxygen.
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 color.
Rubidium nitrate is sold by chemical suppliers, but it's not cheap.
Can be easily prepared by dissolving rubidium carbonate in nitric acid, the recrystallized from the resulting solution. Rubidium hydroxide can also be used.
- Rb2CO3 + 2 HNO3 → 2 RbNO3 + H2 + CO2
- RbOH + HNO3 → RbNO3 + H2O
- Compound collecting
Rubidium nitrate is an oxidizer and should be handled with care.
In closed bottles.
Should be recycled, as rubidium compounds are expensive.
