Read the below Assertion and Reason and choose the correct option. Assertion (A): Bleaching powder is used as an oxidising agent in chemical industries. Reason (R): Bleaching powder is produced by the action of chlorine on dry slaked lime.
Both A and R are true, but R is not the correct explanation of A
Assertion (A): Bleaching powder is used as an oxidising agent. ✓ (True — it releases active chlorine/oxygen which oxidises coloured matter)
Reason (R): Bleaching powder is produced by the action of chlorine on dry slaked lime (Ca(OH)₂ + Cl₂ → CaOCl₂ + H₂O). ✓ (True)
However, R explains the method of preparation, NOT why it acts as an oxidising agent. The oxidising action is due to the release of nascent oxygen/chlorine when it reacts with acidic or moist conditions — this mechanism is NOT stated in R.
Therefore: Both A and R are true, but R is NOT the correct explanation of A.
