**(A):** -factor for in acidic medium is 5. <br> **(R):** In acidic medium, is reduced to . — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Assertion:** Permanganate in acidic medium facilitates a 5-electron transfer. Statement is true. <br>**Reason:** The reduction half-reaction $MnO_4^- + 8H^+ + 5e^- \rightarrow Mn^{2+} + 4H_2O$ shows a change from +7 to +2, which is a gain of 5 electrons. This is the definition of the $n$-factor in this context.
