Question

"Sodium metals when dissolved in ammonia gives a non-conducting solution."
Answer whether the above statement is true or false.
If true enter 1, else enter 0.

Answer 1

Sodium metals when dissolved in ammonia gives a conducting blue coloured solution. This is conductivity is due to presence of solvated electrons.

In dilute solutions, the cation appears to be $N{a}^{+}$, probably solvated as $Na(N{H}_3{)}_{m^{+}}$, and the anion $N{H}_3^{-}$ or ${(N{H}_3{)}_n}^{-}$ which also contributes to the colour.
