Question

name the technique used to separate the following mixture alcohol and water 2) colloidal particles from their solution

Answer 1

1-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 themixture have different boiling points.

2--They cannot be separated from the mixture by the process of filtration. But they can be separated by a specialtechnique called as Centrifugation. Centrifugation method is used for separating suspended particles of substances from a liquid in which the mixture is rotated at high speed in a centrifuge.

Answer 2

alcohol and water can separate by the distillation here fractional distillation don't use because there are two miscible liquids only.
2) colloidal particles separate by filtration
