Ergänzende Hinweise
Definitionpotassium hydride: A white orgreyish white crystalline solid, KH;r.d. 1.43–1.47. It is prepared by passinghydrogen over heated potassiumand marketed as a light grey powderdispersed in oil. The solid decomposeson heating and in contact withmoisture and is an excellent reducingagent. Potassium hydride is a firehazard because it produces hydrogenon reaction with water.
