What is the oxidation state of iodine in $\mathrm{I}_2 \mathrm{Cl}_6$ ?
What is the oxidation state of iodine in $\mathrm{I}_2 \mathrm{Cl}_6$ ?
+7
-3
+3
-2
Solution
Let x be the oxidation state of I in $\mathrm{I}_2 \mathrm{Cl}_6$.
$\begin{array}{ll}
\therefore \quad & 2 x+6 \times(-1)=0 \\
& 2 x-6=0 \\
& 2 x=6 \\
\therefore \quad & x=+3
\end{array}$
