A concentration cell is called such because both the anode and cathode are build from the same components, meaning the standard cell potential is zero volts and the measured cell potential entirely depends on the relative concentration of ions on either side of the electrochemical cell. Consider the following concentration cell Zns)lZn2() (77M)Zn2()(0.50 M)| Znø) 0.50 M) Zn Given that the concentration of zinc ions in the cathode are 0.50 M, what would the concentration of zinc ions need to...
Do measured cell potentials show any effect of solution concentration on cell potential for the reactions performed in this experiment? For example, would the potential have changed for 0.1 M solutions from standard conditions of 1 M solutions. Yes, the Nernst equation shows potential is dependent on solution concentrations. No, the Nernst equation does not show potential is dependent on solution concentrations. The potential would change if the cathode and anode were mislabeled. Potential is dependent on concentration, but in...
Use the Nernst equation to calculate the theoretical value of E of th copper-concentration cell and compare this value with th cell potential you measured. E = E* - 0.0592 / n * logQ **So I believe this is the equation that I would use. However, i'm don't know what E* is suppose to be...** The my electrochemistry experiment the cell potential that i measured were: 0.130V, 0.115V, and 0.110V (average cell potential = 0.118V) The concentration of the copper...
