The process of filtration is driven by which of the following?

• A. Difference in color of the components
• B. Difference in particle size between the components
• C. Difference in boiling points of the components
• D. Difference in solubility of the components

Answer: (B)

Verified step by step guidance

1. Understand that filtration is a physical separation technique used to separate solid particles from a liquid or gas by passing the mixture through a porous material called a filter.
2. Recognize that the key principle behind filtration is the difference in particle size between the components; the filter allows smaller particles or liquid to pass through while retaining larger solid particles.
3. Note that differences in color, boiling points, or solubility are not the driving factors for filtration, although they may be relevant in other separation methods like distillation or extraction.
4. Recall that filtration is commonly used to separate an insoluble solid from a liquid, such as sand from water, based on the solid's inability to pass through the filter pores.
5. Summarize that the process of filtration is driven by the difference in particle size between the components in the mixture.
