Rubidium hydroxide, RbOH






The Rubidium hydroxide, RbOH, is formed by dissolving the metal in water, or by the action of barium hydroxide on rubidium sulphate. It is a very deliquescent substance, and is volatilized by heat. Its melting-point is 301° C., and its density 3.203 at 11° C. The latent heat of fusion per mol. Is 1.614 Cal.; the heat of formation from the elements is 101.99 Cal. A monohydrate and a dihydrate have been described.
