Document Summary
Oxygen usually has an oxidation state of -2. Reducing agents are rich in h, poor in o, metal in low oxidation state. Oxidizing agents are rich in o and poor in h, metal in high oxidation state. Nad+ is the oxidizing agent, accepting electrons to become reduced b. If after multiplying the two bridge half reactions, if the charges arent balanced, you must add either h+ or oh- to one of the sides, depending on if the reaction happens in an acid or base. You must then rebalance the equation by adding water to the opposite side i. c. For example, in h202, 0 must be -1 to create a zero overall charge. Electrochemistry involves the transfer of energy in oxidation reduction reactions. General chemistry page 1 b. c. d. e. f. g. h. reduction reactions. The energetics of half-cells are measured relative to the reduction of hydronoium into hydrogen.
