Find the Oxidation Numbers KClO Since is in column of the periodic table , it will share electrons and use an oxidation state of . Cl is +3 on the left (remember all compounds are 0 so K + Cl + 2O = 0; therefore, 1 + ? We know that potassium (K) has an oxidation of +1 since it is a group 1 element. KCL should have oxidation number of 0 k = +1 and cl = -1. Chlorine has an oxidation state of -1 unless it is bonded to oxygen or fluorine. hcbiochem. ... which ion balance takes place, Cl or K? Since KCl is a neutral molecule, the sum of the oxidation states of the atoms equals zero. Since Cl2O3 is a neutral compound, it has an overall charge of 0, which means that the total oxidation number of the compound is 0. Oxidation number of Cl in HCl/KCl = -1. b) 2K + Cl₂ → 2KCl.
