Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
HCl doesn't used to acidify a $K M n O_{4}$ solutions in volumetric estimations of $F e^{2 +}$ or $C_{2} O_{4}^{2 -}$
as $K M n O_{4}$ oxidizes HCl to $C l_{2}$
$2 M n O_{4}^{-} + 16 H^{+} + 10 C l^{-} \to 5 C l_{2} + 2 M n^{2 +} 8 H_{2} O$
Thus both Assertion and Reason are correct and Reason is the correct explanation for Assertion
