CHLORINE exhibits -1, +1, +3, +5, +7 oxidation states… Chlorine has an oxidation state of -1. In the earlier section, we knew, sulfur atoms are oxidized while chlorine atoms are reduced. Log in. So chlorine atom is reduced from 0 to -1 in the reaction. Interpretation Introduction. Chlorine is a chemical element with atomic number 17 which means there are 17 protons and 17 electrons in the atomic structure.The chemical symbol for Chlorine is Cl. Cl is 1+ here. The ClOH is called chloric(I) acid, or hypochlorous acid. Chlorine is added in drinking water and swimming pools to kill bad bacteria. Ask your question. The oxiding power of HClO4, HClO3, HCLO2, HClO are in the order HClO >HCLO2 >HClO3>HClO4 because the oxidising states of chlorine in HClO4, HClO3, HCLO2, HClO are 7,5,3,1 respectively so HClO with lowest oxidation state of chlorine have greatest tendency to get oxidised and increase its oxidation state. Ask your question. \begin{array}{ll}{\text { a. ClF }} & {\text { c. HCl }} \\ {\text { b. } Since there are 2 O, the total oxidation states for O is 2 x (-2) = -4.
