What is the oxidation number of nitrogen in Al(NO 3) 3? According to rule 4, the sum of the oxidation number on all atoms must equal the charge on the species, so we have the simple algebraic equation. Ba in BaSO4 Halogens in most binary ionic compounds-----Oxidation number is -1 ie. Oxide ions have a -2 oxidation number. H +1 Cl -1 + K +1 Mn +7 O -2 4 → K +1 Cl -1 + Mn +2 Cl -1 2 + H +1 2 O -2 + Cl 0 2 +1 +x+3(-2) =0 (notice we multiplied 3 by -2, because in the formula we have 3 atoms of oxygen with -2 charge each), Therefore, the oxidation number of N in KNO3 is +5. 1 + X + (-2) 3 = 0.
