Question

In which conditions `Na_2O` reacts with `H_2O` to form NaOH?

Answer 1

`Na_2O + H_2O(l) rarr 2NaOH(aq) + Delta`

Explanation:

Sodium oxide is thus the `"base anhydride"` of sodium hydroxide. When you open a tin, the white powder is usually contained in a plastic bag, so that it does not undergo reaction with moist air.
