Which statement is correct regarding the process of filtration?

• A. Filtration is used to separate insoluble solids from a liquid.

• D. Filtration is a method to separate liquids based on boiling points.

Answer: (A)

Verified step by step guidance

1. Understand the concept of filtration: Filtration is a physical separation process used to separate solid particles from a liquid or gas by passing the mixture through a filter medium that allows only the fluid to pass through.
2. Identify the key characteristic of filtration: It is specifically used to separate insoluble solids from a liquid, meaning the solid does not dissolve in the liquid.
3. Differentiate filtration from other separation methods: Filtration is not used for separating soluble substances, as these would pass through the filter with the liquid. It also does not involve evaporation, which is a different process used to separate a solvent from a solution.
4. Clarify the difference between filtration and distillation: Filtration is not used to separate liquids based on boiling points; that process is known as distillation.
5. Conclude with the correct statement: Filtration is used to separate insoluble solids from a liquid, making it the correct statement regarding the process of filtration.
