**(A):** acts as a self-indicator in redox titrations. <br> **(R):** At the equivalence point, the p — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Assertion:** $KMnO_4$ is deep purple. Its reduction product $Mn^{2+}$ is nearly colorless. True. <br>**Reason:** The appearance of the first excess drop of $KMnO_4$ gives a persistent pink color (if $KMnO_4$ is the titrant), marking the end point without external indicators. True and explains the property.
