9.32. Saline hydrides (i.e. CaH2 NaH etc.) react with water and form the corresponding metal hydroxide with the liberation of H2 gas. Thus, these hydrides can be used to remove traces of water from the organic compounds.
NaH (s) + H2O (l) → NaOH (aq) + H2 (g)
CaH2 (s) + 2H2O (l) → Ca (OH)2 (aq) + H2 (g)
