Rubidium nitrite is an inorganic chemical compound with the formula RbNO2.

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.
