Vedclass · Answer

(D) When alkali metals like sodium dissolve in liquid ammonia,they undergo the following reaction: $Na + (x+y)NH_3 \rightarrow [Na(NH_3)_x]^+ + [e(NH_3)_y]^-$. The blue colour of the solution is due to the excitation of solvated electrons to higher energy levels,which absorb light in the red region of the visible spectrum. The solution is highly conducting due to the presence of both solvated cations $[Na(NH_3)_x]^+$ and solvated electrons $[e(NH_3)_y]^-$. Therefore,both statements $A$ and $B$ are correct.
