Question

What happens when sodium is treated with nh3?​

Answer 1

$‌\huge \underline{ \bf { \red{\ \: Answer}}}$

By the reaction of sodium with liquid ammonia sodium amide can be prepared. Sodium(alkali metal) dissolves dissolves in liquid ammonia solution to form a blue solution characteristic of a solvated electron in liquid ammonia, which is conducting in nature, due to ammoniated electrons (solvated electron).

The redox chemistry of sodium in liquid ammonia is fairly complex. Solvated electrons form (to give the blue colour). As more metal is added the electrons COUPLE to form bronzes, reducing conductivity. Diluted solutions are deep blue coloured while concentrated are bronze coloured.
