Water can be separated from alcohol water mixture by
A). Decantation
B). Evaporation
C). Distillation
D). Sublimation
Distillation
To separate a mixture of alcohol (ethanol) and water, you can use a process known as fractional distillation. This technique relies on the fact that the compounds in the mixture have different boiling points. Since ethanol boils at a lower temperature (78.5 degrees Celsius) than water, the alcohol vaporizes while most of the water remains a liquid.
