Question

Assertion: Bleeding from a fresh cut can be stopped by applying potash alum.

Reason: Alum heals the wound created by the cut.

• A. Both assertion and reason are correct and the reason is the correct explanation of the assertion.
• B. Both assertion and reason are correct but the reason is not the correct explanation of the assertion.
• C. Assertion is correct but the reason is incorrect.
• D. Assertion is incorrect but the reason is correct.

Answer 1

The correct option is C

Assertion is correct but the reason is incorrect.

Explanation for assertion statement:

This statement is true because bleeding from a fresh cut can be prevented using Potash Alum by rubbing its crystals on the wound.

Explanation for reason statement:

This statement is not true as-

1. Alum does not heal the wound produced by the cut.
2. The sulphate ions(SO₄^2-) present in Alum help precipitate the positively charged hemoglobin present in the blood which blocks the outflow of blood from the wound.

Hence, the assertion is correct but the reason is incorrect.

Therefore, option C is correct.
