JEE Main 2024 — 6 April, Shift 1 — Question 77

The difference in the 'spin-only' magnetic moment values of $\mathrm{KMnO}_{4}$ and the manganese product formed during titration of $\mathrm{KMnO}_{4}$ against oxalic acid in acidic medium is $\qquad$ BM. (nearest integer)

Answer: 6

Numerical answer — enter this value.

Step-by-step solution

Spin only magnetic moment of Mn in $\mathrm{KMnO}_{4}=0$ Spin only value of manganese product fromed during titration of

$\mathrm{KMnO}_{4}$ aganist oxalic acid in acidic medium is $=6$
