Explain the following:The solution of alkali metals in liquid ammonia is blue in colour. |
|
Answer» The alkali metals dissolve in liquid ammonia giving deep blue solutions M +(x +y)NH3= [M(NH3 )x ]+ + [e (NH3 )y ]- The blue colour of the solution is due to the ammoniated electron which absorbs energy in the visible region of light and thus imparts blue colour to the solution. |
