• 5

Answer 1

In the reaction of oxalate with permanganate in an acidic medium, the number of electrons involved in producing one molecule of CO₂ is 1.

Explanation:

Reaction involved:

\[\ce{\overset{+3}{C}_2O^{2-}_4 -> 2\overset{+4}{C}O2 + 2e^-}\]

∴ The number of electrons involved in producing one mole of CO₂ is 1.
