# Given the following equation: HClO2+H2O--> H2O + ClO2, how would you identify the acid, base, conjugate acid, and conjugate base?

$H C l {O}_{2} + {H}_{2} O r i g h t \le f t h a r p \infty n s C l {O}_{2}^{-} + {H}_{3} {O}^{+}$
So what is the oxidation state of chlorine in this chlorous acid? This is a weak acid as acids go; perchloric acid $H C l {O}_{4}$ (oxidation state of $C l$?) is much stronger; why?
