Understanding +4 | -1

Assertion: Equivalent weight of

\mathrm{KMnO}_4

in acidic medium is

\frac{\mathrm{M}}{5}

.
Reason: In acidic medium 1 mol of

\mathrm{MnO}_4^{-}

gains 5 electron.

View answer and explanation

Correct option: A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion

Option A (If both Assertion and Reason are correct and Reason is the correct explanation of Assertion) is correct because in acidic medium, permanganate ion (

MnO_4^−

) gains 5 electrons, and this directly explains why the equivalent weight is M/5.
