Chemistry - Redox Reactions Question with Solution | TestHub

The given compound is ${\mathrm{I}}_2{\mathrm{Cl}}_6$, which is a dimer of iodine trichloride (${\mathrm{ICl}}_3$).

Chlorine is more electronegative than iodine, so its oxidation state is $-1$.

Let the oxidation state of iodine be $x$.

In ${\mathrm{I}}_2{\mathrm{Cl}}_6$, the sum of oxidation states of all atoms must be zero:

$2x+6(-1)=0$

$2x-6=0$

$2x=6$

$x=+3$

Therefore, the oxidation state of iodine in ${\mathrm{I}}_2{\mathrm{Cl}}_6$ is $+3$.

Answer: +3
