Vedclass · Answer

(C) To find the oxidation number of chlorine $(Cl)$ in each compound,we use the rule that the sum of oxidation numbers in a neutral molecule is $0$. Let the oxidation number of $Cl$ be $x$. The oxidation number of $H$ is $+1$ and $O$ is $-2$.For $HClO_3$:$1 + x + 3(-2) = 0$$1 + x - 6 = 0$$x - 5 = 0$$x = +5$.Therefore,in $HClO_3$,the oxidation number of chlorine is $+5$.

Select the compound in which chlorine is assigned the oxidation number $+5$.
