Description :
Mp: 300-302°C
Rubidium hydroxide (RbOH) is a strong basic chemical and alkali that is formed by one rubidium ion and one hydroxide ion.
Rubidium hydroxide does not appear in nature. However it can be obtained by synthesis from rubidium oxide. In addition, rubidium hydroxide is commercially available in form of an aqueous solution from a few suppliers.
Rubidium hydroxide is highly corrosive, therefore suitable protective clothing, gloves and eye-face protection are required when handling this material.
Rubidium hydroxide can be synthesized from rubidium oxide by dissolving the oxide into water:
Rb2O (s) + H2O (l) → 2 RbOH (aq)
Rubidium hydroxide is also commercially available from a certain number of chemical suppliers in form of 50% or 99% aqueous solution at multiples of 5 g.
