Question

Four $C{l}_2$ molecules undergo a loss and gain of $6$ mole of electrons to form two oxidation states of $Cl$ in auto redox change. What are the $+ve$ and $-ve$ oxidation states of $Cl$ in the change:

• A. $C{l}^{5+},C{l}^o$
• B. $C{l}^{7+},C{l}^{-}$
• C. $C{l}^{3+},C{l}^o$
• D. $C{l}^{3+},C{l}^{-}$

Answer 1

The correct option is D $C{l}^{3+},C{l}^{-}$

The overall reaction is:

$4{Cl}_2\to 2{Cl}^{+3}+6{Cl}^{-}$

Here total number of atom is balanced and total charge is balance.

Change of oxidation state is +3 and -1.
