Security:
Rubidium hydroxide is highly corrosive and can burn on contact. Therefore, it must be handled carefully.

Physical and chemical properties:
Rubidium hydroxide is a strong base, which is more alkaline than potassium hydroxide. It is a white solid, easy to hydrolyze, and has basic connectivity. It can react with CO2 in the air to form rubidium carbonate

Use:
Hydroxide rubidium seldom used in industrial production, are used for making metal rubidium and various rubidium salts material, catalyst, miniature high energy battery, including rubidium single crystal materials, special glass and ceramic industry and other fields. Because of the high price and the main use can be replaced by potassium hydroxide and sodium hydroxide, which are both mild and safe to operate.

Preparation:
Rubidium oxide is dissolved in water to form rubidium hydroxide
Equation: Rb2O+H2O=2RbOH
Rubidium sulfate and barium hydroxide react to form barium sulfate precipitation and rubidium hydroxide
The equation is: Rb2SO4+Ba(OH)2=2RbOH+BaSO4
