Question

Why is the solution of NaH in water alkaline?

Answer 1

Answer:

This reaction happens with a large equilibrium constant, so we can say that NaH almost completely dissociates when placed into an aqueous solution. This makes it a strong base. This reaction doesn't happen because sodium has a lower electronegativity than hydrogen.

Hope you got it....

Answer 2

Because it dissolves easily in water, Thus it is alkaline.
