Rubidium nitrite is an inorganic chemical compound with the formula RbNO2.
Contents
Properties
Chemical
Rubidium nitrite is an oxidizer, albeit a weaker one compared to rubidium nitrate, and mixtures with flammable materials will burn if ignited with an open flame.
In a flame test, RbNO2 gives a mauve/light purple color.
Physical
Rubidium nitrite is a colorless solid, soluble in water.
Availability
Rubidium nitrite is hard to find, and when it's available, it's quite expensive.
Preparation
Rubidium nitrite can be prepared by adding a solution of rubidium carbonate to a solution of barium nitrite. The resulting BaCO3 is filtered off and the rubidium nitrite is recrystallized from solution.
Rubidium nitrate will decompose above 300-310 °C to yield rubidium nitrite and oxygen.
Projects
- Compound collecting
Handling
Safety
Rubidium nitrite, like all nitrites may be harmful if ingested.
Storage
In closed bottles
Disposal
Best to try and recycle it, as rubidium is expensive.
