The Total solution for NCERT class 6-12
Saline hydrides (i.e, CaH2 NaH etc.) react with water and form thecorresponding metal hydroxide with the liberation of H2 gas. Thus, these hydrides can be used to removetraces of water from the organic compounds.NaH(s) + H2O(l) ———–> NaOH(aq) + H2(g)CaH2(s) + 2H2O(l) ———> Ca(OH)2(aq) + H2(g)
