Rubidium hydroxide chemical Properties,Uses,Production

Chemical Properties

clear colorless equipment

Physical properties

Grayish-white orthogonal crystals; hygroscopic; thickness 3.2 g/cm3; melts at 301°C; an extremely soluble in water (100 g/100 mL in ~ 15°C), the solution extremely alkaline; soluble in ethanol.


Catalyst in oxidative chlorination.


Rubidium hydroxide might be obtained as an intermediate in recovering rubidium steel from mineral lepidolite (see Rubidium). In the laboratory it may be prepared by adding barium hydroxide come a equipment of rubidium sulfate. The insoluble barium sulfate is separated by filtration:Rb2SO4 + Ba(OH)2 → 2RbOH + BaSO4Preparation must be in nickel or silver- containers because rubidium hydroxide assaults glass. The systems is focused by partial evaporation. The advertisement product is generally a 50% aqueous solution.

General Description

A clean aqueous solution. Very caustic. Really irritating come skin and also eyes. Supplied in electrical storage batteries.

Air & Water Reactions

Absorbs carbon dioxide from the air. Might generate big amounts of warmth when diluted v water.

Reactivity Profile

A solid base. Creates caustic systems in water .


strong irritant come tissue.

Health Hazard

TOXIC; inhalation, sloop down or skin contact with material may cause severe injury or death. Contact with molten substance may reason severe burns come skin and eyes. Avoid any skin contact. Impacts of contact or inhalation may be delayed. Fire may create irritating, corrosive and/or toxicity gases. Runoff indigenous fire manage or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxicity fumes. Some room oxidizers and also may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals might evolve flammable hydrogen gas. Containers might explode as soon as heated.

Safety Profile

Moderately toxicity by ingestion. A powerful, corrosive irritant to skin, eyes, and mucous membranes. When heated come decomposition the emits toxicity fumes the RbzO. See additionally POTASSIUM HYDROXIDE and RUBIDIUM.
