Question

Alkali metals dissolve in liquid ammonia and produces _______.

• A. deep blue solution
• B. a solution which are conducting in nature
• C. red coloured solution
• D. Both $1$ and $2$

Answer 1

Answer: (D)

Both $1$ and $2$

Alkali metal when reacts with liquid ammonia reaction is given by,

$M+(x+y)N{H}_3\to M^{+}\left(N{H}_3\right)x+e^{-}(N{H}_3{)}_y$

this electrons is free and gives very good conductivity as well blue colour.
