Enthalpy refers to the total energy of a system. Enthalpy is basically a thermodynamic unit of measurement that determines the total heat content of a system. This means that all energy is included in the measurement - the energy used to make the system, the energy of the system, and the energy it uses to keep the environment separate from the system.

If you had a mixture of ethanol, glycerol, ethylene glycol, methanol, and water, how could you separate these five substances ou

leonid [27]

Fractional distillation

Explanation:

The best way to separate the mixtures out is through the process of fractional distillation.

In fractional distillation, liquid - liquid mixtures are separated based on the differences in boiling point of their components. Let us examine the boiling points of the component of the mixtures:

Ethanol 78⁰C

Glycerol 290⁰C

Ethylene glycol 197.6⁰C

Methanol 64.7⁰C

Water 100⁰C

We see that the liquids in the mixture have different boiling points. In this process, the mixture is heated in a distillation column. When the boiling point of any component is reached, it will rise up in the column and can be channeled to a condenser where it is cooled and collected.

The liquid with the least boiling point is first separated with the one with the highest boiling is recovered last:

Order of recovery;

Methanol 64.7⁰C

Ethanol 78⁰C

Water 100⁰C

Ethylene glycol 197.6⁰C

Glycerol 290⁰C
