Chemistry - Redox Reactions Question with Solution | TestHub

To find the value of $(x+y)$, we balance the given redox reaction by charge and atoms:

Charge Balance: The total charge on the left ($-6$ from $6O{H}^{-}$) must equal the total charge on the right ($-1$ from $Cl{O}_3^{-}$ and $-y$ from $yC{l}^{-}$).

Find $y$: Solving $-6=-1-y$ gives $y=5$.

Atom Balance: The total number of Chlorine atoms on the left ($2x$) must equal those on the right ($1+y$).

Find $x$: Substituting $y=5$ into $2x=1+5$ gives $2x=6$, so $x=3$.

Final Answer: Therefore, $x+y=3+5=8$.
