Vedclass · Answer

(C) When alkali metals $(M)$ dissolve in liquid ammonia,they undergo ionization as follows: $M + (x+y)NH_3 \rightarrow [M(NH_3)_x]^+ + [e(NH_3)_y]^-$. The blue color of the solution is due to the presence of ammoniated electrons,which absorb energy in the visible region of light corresponding to the red part,resulting in the transmission of blue color. Therefore,the correct option is $C$.
