Chem 122: general chemistry ii - lecture 19: electrochemistry ii (11. 1, 11. 2, 11. 3, and 11. 4) Accordingly, the reaction between fe2+ and cl2 would be spontaneous (positive. In other words if we did reaction in a beaker containing a solution of aqueous. Febr2 and we bubbled cl2 gas into the solution, aqueous fecl3 would be produced. First thing to consider are the species present (na+ , i- , and br2). Na+ is in it"s fully oxidized form (i. e. it won"t be oxidized any further), it can only be reduced potential cathode reaction. I- is in it"s fully reduced form (i. e. it won"t be reduced any further), it can only be oxidized potential anode reaction. Br2 is in it"s fully oxidized form (i. e. it won"t be oxidized any further), it can only be reduced potential cathode reaction. E cell = (1. 09 v) - (0. 54 v) = 0. 55 v (a positive cell potential)
