Cesium hydroxide,CsOH,also known as cesium hydrate, is a colorless to yellowish deliquescent solid.It is formed by the vigorous reaction of cesium and water.Cesium hydroxide is the strongest of the alkali metal hydroxides with the lowest lattice energy. It is soluble in water.Cesium hydroxide is used as an electrolyte in alkaline batteries at subzero temperatures.
Cesium hydroxide (CsOH) is the strongest base (alkali) with the highest pH value of any
chemical yet found. It is easy to produce by just placing cesium metal in water (which is very
reactive). After the hydrogen escapes, cesium hydroxide remains in the water (2Cs + H2 →
2CsOH + H2).
ChEBI: Caesium hydroxide is an alkali metal hydroxide and a caesium molecular entity.
