trighloroethane is a slvent used to remove grease from clothings. how, after use, is the solvent separated form the grease?

a, chromatography
b, crystallisation
c, distillation
d, filtration

c. TCE (thrichloroethane) is very volatile. It evaporates and leaves the grease behind. The TCE solvent vapor is collected and recondensed. That is called distillation.

thanks

You're welcome! Distillation is indeed the correct answer. After the trichloroethane (TCE) solvent is used to remove grease from clothing, the separation process involves distillation.

Distillation is a method of separating two or more substances based on their differences in boiling points. In this case, TCE is a volatile compound, meaning it has a low boiling point and readily evaporates. The TCE solvent is heated, causing it to vaporize and leave the grease behind.

The TCE vapor is then collected and cooled down in a condenser, which causes it to condense back into a liquid form. This condensed TCE can be collected and reused, while the separated grease remains behind.

So, in summary, the separation of the solvent (TCE) from the grease is achieved through distillation.
