Rectified spirit is converted into the absolute alcohol by _.
Correct answer: C. Re-distillation
- A. Crystallization
- B. Distillation
- C. Re-distillation
- D. Fractional distillation
Explanation
c) Re-distillation: Re-distillation is essentially the same as distillation. It is the process of distilling a liquid multiple times to achieve higher purity. In the case of converting rectified spirit into absolute alcohol, the process would involve re-distillation.

About Sublimation and Distillation
Sublimation separates a sublimable solid from non-sublimable impurities by direct conversion between solid and vapour, followed by deposition. Distillation separates liquids through differences in boiling points, including simple, fractional, steam and vacuum distillation, and the choice depends on volatility, miscibility and thermal stability.
