which methods seperate a mixture according to the size of the particles

Question

A. Filtration and evaporation
B. Distillation and chromatography
C. Filtration and chromatography
D. Distillation and evaporation

Answer 1

A. Filtration and evaporation

Filtration is a method that separates mixtures based on particle size, allowing smaller particles to pass through while larger particles are retained. Evaporation can also separate components of a mixture based on boiling points, but it's not primarily about particle size. Therefore, the best answer focusing on particle size is that filtration is the main method used, but in the context of your options, none of them categorize as strictly size-separation methods beyond filtration.

If you strictly focus on particle size separation, the better answer among the given options is C. Filtration and chromatography, where chromatography can also involve separation based on particle size or other properties in some contexts.

However, filtration is definitely the primary method of particle size separation.

Answer 2

Are you sure

Answer 3

I apologize for any confusion in my previous response. Let's clarify.

When it comes to separating mixtures specifically by particle size, the most relevant method is filtration.

Here's a brief overview of the methods mentioned:

• Filtration: Separates solids from liquids or gases based on particle size. Larger particles are trapped by the filter while smaller particles pass through.

• Evaporation: Used primarily to separate a solute from a solvent, usually by turning the solvent into vapor, but it doesn't focus on particle size.

• Distillation: Separates liquids based on differences in boiling points, not particle size.

• Chromatography: Can separate substances based on various properties, including size, but is more commonly associated with differences in affinity for the stationary phase versus the mobile phase.

Given your options, the correct one for separating based predominantly on particle size is indeed:

C. Filtration and chromatography.

Filtration is the primary method for particle size separation, while chromatography can also involve size differences, especially in specific techniques like size-exclusion chromatography.

Thank you for your patience, and I hope this clarifies the answer!
