WebThe average oxidation state of the sulfur atoms is therefore +2 1 / 2. STEP 3: Determine which atoms are oxidized and which are reduced. STEP 4: Divide the reaction into oxidation and reduction half-reactions and balance these half-reactions one at a time. This reaction can be arbitrarily divided into two half-reactions. WebThe half-reaction method for balancing redox equations provides a systematic approach. In this method, the overall reaction is broken down into its half-reactions. Each half-reaction is then balanced individually, and then the half-reactions are added back together to form a new, balanced redox equation.
