Vedclass · Answer

(C) Rectified spirit contains approximately $95.6 \%$ ethanol and $4.4 \%$ water by mass,which forms a constant boiling azeotropic mixture. To obtain absolute alcohol ($100 \%$ pure ethanol),the water must be removed. This is commonly achieved by the azeotropic distillation method,where benzene is added to the mixture. Benzene forms a ternary azeotrope with water and ethanol,allowing the water to be removed as a distillate,leaving behind absolute alcohol.
