Radium hydroxide is an inorganic compound of radium, hydrogen, and oxygen with the chemical formula Ra(OH)2. [1] Stability constant of aqueous RaOH+ ion pair at zero ionic strength is equal to 5. [2]
Radium hydroxide forms colorless crystals that dissolve in water better than does barium hydroxide, and has more basic properties.
The compound forms a hydrate of the composition Ra(OH)2·8H2O. [3]
Radium hydroxide is a caustic, toxic, and corrosive substance. It is significantly more toxic than barium hydroxide (Ba(OH)2) and strontium hydroxide (Sr(OH)2).
