(B) Step $1$: Calculate the oxidation state of $Cl$ in $ClO_4^-$. Let the oxidation state be $x$. $x + 4(-2) = -1 \implies x - 8 = -1 \implies x = +7$.Step $2$: Calculate the oxidation state of $Cl$ in $ClO_2^-$. Let the oxidation state be $y$. $y + 2(-2) = -1 \implies y - 4 = -1 \implies y = +3$.Step $3$: Calculate the change in oxidation state per $Cl$ atom: $|7 - 3| = 4$.Step $4$: For $n$ moles of $ClO_4^-$, the total number of electrons gained is $4 	imes n = 4n$.

What is the number of electrons gained by $Cl$ atom when $n$ mole of $ClO_4^-$ is transformed into $n$ mole of $ClO_2^-$ ion?
