Which method of separation involves the use of a solvent to separate components based on their solubility?

Extraction

Explanation

Solvent-based separation by solubility differences.

Which of the following techniques is NOT used for the separation of mixtures?

Electrolysis

Explanation

Electrolysis is not a separation technique; it involves chemical decomposition.

What is the primary principle behind the separation technique of filtration?

Particle size differences

Explanation

Separating based on particle size variances.

Which method of separation involves heating a mixture to vaporize one component and then condensing the vapor back into a liquid?

Distillation

Explanation

Vaporizing and condensing to separate components.

What is the primary principle behind the separation technique of evaporation?

Heating to vaporize volatile components

Explanation

Separating via heating volatile components.

What is the principle behind the separation technique of distillation?

Differences in boiling points

Explanation

Separating components based on boiling point disparities.

What is the purpose of a separating funnel in extraction?

To separate immiscible liquids

Explanation

Facilitating separation of liquids that don't mix.

What is the primary principle behind the separation technique of chromatography?

Differences in adsorption or partitioning

Explanation

Separation based on differential adsorption.

In centrifugation, which property is utilized to separate components of a mixture?

Density

Explanation

Utilizing density variations for separation.

#10

What is the primary principle behind the separation technique of sublimation?

Direct transition from solid to vapor

Explanation
