Question

3- you are required to seprate ethanol ( boiling point =78 C) from a mixture having 3 wt% ethanol and 97 wt% water (boiling point=100 C) at 1 atm. the mixture will not form azeotrope in the condition of operation . you need to choose a process between adsoprtion and solvent extraction for the job . which process would you choose and why ?

Explanation / Answer

The process that you are looking for is ''Distillation"

Distillation is the extraction of the essential.

as you know the both solvent boiling point so it would be very easy for you to separate them out with distillation process.

condenser is the appratus that you need to find to separate out the water and ethanol from the solution.

for that you need round bottom flask, one T pipe and thermometer and you need to heat your solution.

once it will reach round 78 then ethanol will separate out in another separate beaker and remaining part will be the water in your round bottom flask.
