Example 1: This is the reaction between magnesium and hydrochloric acid or hydrogen chloride gas: ASSIGNING OXIDATION NUMBERS TO ELEMENTS Review The sum of all oxidation numbers in a compound or ion must equal the net charge on that compound or ion. Chlorine is added in drinking water and swimming pools to kill bad bacteria. When using Lewis formula to assign oxidation states, all the electrons in each bond are assigned to the more electronegative atom in the bond. stream But here Cl- is on its own, so is it a 0 or -1 oxidation number? : Cr 2O7 2-+ 14 H + + 6 e-2 Cr 3+ + 7 H 2O (2) b) Oxidation von H 2SO 3 mit Cr 2O7 22--Oxidation und Reduktion II. Expert Answer 100% (46 ratings) Previous question Next question Transcribed Image Text from this Question. There are a few exceptions to this rule: When oxygen is in its elemental state (O 2), its oxidation number is 0, as is the case for all elemental atoms. Cl 0 2 + O -2 H +1 - → Cl +5 O -2 3 - + Cl -1 - … See the answer.
