A galvanic cell at a temperature of 25.0°C is powered by the following redox reaction: Cu2+(aq) + Zn(s) --> +Cu(s) + Zn2+(aq) Suppose the cell is prepared with 5.20 M Cu2+ in one half-cell and 3.49 M Zn2+ in the other. Calculate the cell voltage under these conditions. Round your answer to 3 significant digits.
In a galvanic cell, a spontaneous redox reaction occurs. However the reactants are separated such that the transfer of electrons is forced to occur across a wire. The resulting electricity is measured in volts (V) and is the sum of the potentials of the oxidation and reduction half-reactions: E^o cell = E^o red + E^o ox By reversing the reduction half-reactions, you get the corresponding oxidation half-reaction, for which E^o ox has the opposite sign of E^o red You can...
