Question

Assertion: Chalk powder can be separated from water by filtration.

Reason: Chalk powder is insoluble in water.

Which amongst the following is correct regarding these statements?

• A. Assertion is true and reason is its correct explanation.
• B. Assertion is false but reason is true.
• C. Both assertion and reason are false.
• D. Both assertion and reason are true, but reason is not its correct explanation.

Answer 1

The correct option is A Assertion is true and reason is its correct explanation.

$\bullet$ Filtration is used for separating insoluble solids from a liquid. To carry out filtration, a filter paper is used. This paper allows the liquid to pass through while holding back the insoluble solid.
$\bullet$ Chalk powder is insoluble in water, so it will not pass through the filter paper. Whereas, water will pass through and hence, filtration can be used for this separation.
