Vedclass · Answer

(B) The correct answer is $(B)$.When alkali metals like sodium dissolve in liquid ammonia,they undergo ionization to form ammoniated cations and ammoniated electrons.The reaction is: $Na + (x + y)NH_3 	o [Na(NH_3)_x]^+ + [e(NH_3)_y]^-$.The blue colour of the solution is primarily due to the presence of solvated electrons $([e(NH_3)_y]^-)$,which absorb energy in the visible region of the spectrum.

When sodium metal is dissolved in liquid ammonia,a blue-coloured solution is formed. The blue colour is due to:
