A) tin
B) lead
C) sodium
D) silver
Correct Answer: C
Solution :
Alkali metals dissolve in liquid \[N{{H}_{3}}\] to give deep blue coloured solution. \[M+\underset{excess}{\mathop{N{{H}_{3}}}}\,\xrightarrow{{}}{{M}^{+}}{{(N{{H}_{3}})}_{x}}+{{e}^{-}}\underset{ammoniated\,electron}{\mathop{{{(N{{H}_{3}})}_{x}}}}\,\] The blue colour of the solution is due to the ammoniated electrons.You need to login to perform this action.
