Statement -1 : Alkali metals dissolve in liquid ammonia to give blue solutions.
Statement -2 : Alkali metals in liquid ammonia give solvated species of the type [M(NH 3 ) n ] + (M = alkali metals).
Text Solution
Verified by ExpertsThe correct answer is:
B
Alkali metals dissolves in liquid ammonia to give ammoniated cations and ammoniated electrons, the blue colour of the solution is due to ammoniated electrons.
M + (m + n)NH 3 → [M(NH 3 ) n ] + + [e(NH 3 ) m ] –
The conductivity of solution is due to both the ions.
