Question

State the reaction of alkali metals with solutions of liquid ammonia.

Answer 1

$\huge\underline\mathscr\red{Answer}$ $\huge\orange{Reaction\:With\:Ammonia}$

• The alkali metals dissolve in liquid ammonia and give deep blue solutions which are conducting in nature.
• These solutions are paramagnetic in nature.
• On standing slowly they liberate hydrogen resulting in the formation of halide.

Answer 2

$\huge{\boxed{\boxed{\mathfrak{\red{Answer}}}}}$

All alkali metals dissolves in liquid ammonia and produce blue coloured solutions which are conducting and reducing in nature due to presence of ammoniated electron.The ammoniated electron which absorbs energy in the visible region of light and thus imparts blue colour to the solution. The solutions are paramagnetic and on standing slowly liberate hydrogen resulting in formation of amide. and In concentrated solution ,the blue colour changes into Bronze colour and becomes dimagnetic.
