Vedclass · Answer

(D) The chemical formula for perchloric acid is $HClO_4$. Let the oxidation state of chlorine $(Cl)$ be $x$. The oxidation state of hydrogen $(H)$ is $+1$ and oxygen $(O)$ is $-2$. Applying the sum of oxidation states equal to zero: $1 + x + (4 	imes -2) = 0$ $1 + x - 8 = 0$ $x - 7 = 0$ $x = +7$. Therefore,the oxidation state of chlorine in $HClO_4$ is $+7$.

The oxidation state of chlorine in perchloric acid $(HClO_4)$ is:
