Hydrides of group 1, such as KH, contain the H- ion.
They react with water to form:
H- + H2O --> H2 + OH-
hydrogen and hydroxide ions ...
Interestingly, this is an example of a synproportionation (comproportionation) reaction where one element in two different oxidation states becomes the same oxidation state. It is the chemical opposite of disproportionation.
