Appearance: Rubidium hydroxide (CAS NO. 1310-82-3) is clear colorless solution .

1. Rubidium hydroxide (CAS NO. 1310-82-3) is rarely used in industrial processes because potassium hydroxide and sodium hydroxide can perform nearly all the industrial functions of rubidium hydroxide in a less violent and hence safer way.
2.Rubidium hydroxide (CAS NO. 1310-82-3) is used in scientific research. It is often used sparingly to prevent waste of the expensive element rubidium.
3.Despite the fact that rubidium hydroxide is rarely used in normal industrial processes, it is notable that the synthesis of nearly all rubidium compounds involves rubidium hydroxide as an intermediate. Natural rubidium oxide is added to water, and the resulting reaction forms soluble rubidium hydroxide as a product.

Rubidium hydroxide can be synthesized from rubidium oxide by dissolving the oxide into water:
Rb₂O (s) + H₂O (l) → 2 RbOH (aq)

Reported in EPA TSCA Inventory.

Moderately toxic by ingestion. A powerful, corrosive irritant to skin, eyes, and mucous membranes. When heated to decomposition it emits toxic fumes of Rb₂O. See also POTASSIUM HYDROXIDE and RUBIDIUM.

DOT Classification:  8; Label: Corrosive

1.General Description: A clear aqueous solution. Very caustic. Very irritating to skin and eyes. Used in electric storage batteries.
Air & Water Reactions: Absorbs carbon dioxide from the air. May generate large amounts of heat when diluted with water.
2.Reactivity Profile A strong base. Forms caustic solution in water .
3.Health Hazard :TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
4.Fire Hazard : Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
