Answer whether the above statement is true or false.
If true enter 1, else enter 0.

Answer 1

Sodium metal when dissolved in ammonia conducts electricity because of solvated electrons.

Sodium metals when dissolved in ammonia gives a conducting blue coloured solution due to the presence of solvated electrons $(e^{-},N{H}_3)$, which are not attached to single atoms. A solvated electron is loosely associated with a cavity in the ammonia solvent that is stabilized by hydrogen bonds. In dilute solutions, the cation appears to be $N{a}^{+}$, probably solvated as $Na(N{H}_3{)}_{m^{+}}$, and anion $N{H}_3^{-}$ or $(N{H}_3{)}_{n^{-}}$ which also contributes the colour.

The presence of solvated electrons $(e^{-},N{H}_3)$ in solutions of alkali metals in liquid ammonia is indicated by the intense color of the solution and its electrical conductivity.
