Ammonia undergoes self dissociation according to the reaction 2NH3(l)⇔NH+2(am)+NH−2(am) where am, stands for ammoniated. When 1 mol of NH4 CI is dissolved in 1 kg of liquid ammonia, the b.p. at 760 torr is observed as −32.7∘C (normal boiling b.p. of NH3(l) is 33.4∘C). What conclusion is reached about the nature of the solution
