Q.
In the reaction of oxalate with permanganate in acidic medium, the number of electrons involved in producing one molecule of $CO _{2}$ is
Some Basic Concepts of Chemistry
Solution:
Reaction of oxalate with permanganate in acidic medium.
$5 C _{2} O _{4}^{2-}$ ions transfer $10 e^{-}$to produce $10$ molecules of $CO _{2}$.
So, number of electrons involved in producing $10$ molecules of $CO _{2}$ is $10$.
Thus, number of electrons involved in producing $1$ molecule of $CO _{2}$ is $1$.
