The blue colour of the solution (metal dissolved in liquid ammonia) is due to :A. free electronsB. paramagnetic nature of solutionC. ammoniated electronsD. liberation of hydrogen from solution on standing |

Answer» Correct Answer - C Ammoniated `e^(-)` absorbs energy in the visible region of light and thus imparts blue colour to the solution. `M+(x+y)NH_(3)rarr[M(NH_(3))_(x)]^(+)+[e(NH_(3))_(y)]^(-)` `M_((am))^(+)+e^(-)NH_(3)(l)rarrMNH_(2(am))+(1)/(2)H_(2)(g)` |
