Step-by-Step Solution:1. Definition of Absolute Alcohol: - Absolute alcohol is defined as 100% pure ethyl alcohol (ethanol). It contains no water or other impurities.2. Chemical Composition</
Ethanol is normally concentrated by distillation of aqueous solutions, but the composition of the vapor from aqueous ethanol is 96 percent ethanol and 4 percent water. Therefore, pure ethanol cannot be obtained by distillation. Commercial ethanol contains 95 percent by volume of ethanol and 5 percent...
