Caesium hydroxide or cesium hydroxide (CsOH) is a chemical compound consisting of an ion of caesium and a hydroxide ion. It is a strong base (pKb=-1.76) much like other alkali metal hydroxides such as sodium hydroxide and potassium hydroxide. In fact caesium hydroxide is powerful enough to quickly corrode through glass.Due to its high reactivity caesium hydroxide is extremely hygroscopic.
