WebEach half-reaction is written to show what is actually occurring in the system; Zn is the reductant in this reaction (it loses electrons), and Br 2 is the oxidant (it gains electrons). Adding the two half-reactions gives the overall chemical reaction (Equation 19.1).A redox reaction is balanced when the number of electrons lost by the reductant equals the … WebThe second reaction is reversed in the overall redox reaction, so its voltage changes sign from the reduction reaction: Cu → Cu 2+ + 2 e − E 1/2 = −0.34 V. To obtain the voltage of the voltaic cell based on the overall reaction, we simply combine the two voltages of the half reactions: E = 0.96 + (−0.34) = 0.62 V how to run userbenchmark
