WebCaesium hydroxide is a strong base (pK a = 15.76) containing the highly reactive alkali metal caesium, much like the other alkali metal hydroxides such as sodium hydroxide and potassium hydroxide. Caesium hydroxide is corrosive enough to quickly dissolve through glass. [7] Due to its high reactivity, caesium hydroxide is extremely hygroscopic. http://barbara.cm.utexas.edu/courses/ch302s09/files/CH302_021609a.pdf griffith gallery
