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 WebCr+3 + Cl-1 = Cr+3 + Cl-12. To balance the unbalanced chloride molecule charges, we add 2 in front of the chloride on L.H.S. We get, Cr+3 + (2)Cl-1 = Cr+3 + Cl-12. Now, the equation is balanced with 2 Chloride’s (Cl) with total charge -2 and 3 Chromium’s with total charge +3 on both sides. This is how the redox equations are balanced.
