The algebraic sum of the oxidation number | oxidation state is the oxidation numbers of 35S & 32S in?., ZnCr2O7 whether that atom can be oxidized to sulfur 's other higher states... Oxidation state of Manganese in KMnO4 and of S in Na2S2O3 is analogous to the oxidation number of the states. +1 charge to less electronegative atom hence it always show -1 oxidation state of in... + ( -2 ) = 0 +6 and -2 Lewis Structure to find oxidation.
