Question
Mesured: Re-enter the values from Part A, column 2. Reduction potential (experiment): Enter the Reduction potential for each redox couple relative to -0.79V for the Zn^2+ (0.1 M)/Zn redox couple. Use E_M = E + (-079V), assuming Zn as the anode. Reduction potential (theoretical). Enter the Reduction potential for each redox couple(M^2/M) as calculated from a table of standard Reduction potential and the Nearest question for [M^2+] = 0.10 M. Error See Appendix B. Reduction potential of the unknown redox couple: Effect of Concentration Changes on cell Potential Cell potential of concentration cell: Anode reaction: Cathode reaction: Explain why a potential is recorded. Cell potential from complex formation: observation of solution in half-cell. cell potential from precipitate formation: Observation of solution in half-cell.Explanation / Answer
A galvanic cell, or voltaic cell, named after Luigi Galvani, or Alessandro Volta respectively, is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell.
The Nernst Equation enables the determination of cell potential under non-standard conditions. It relates the measured cell potential to the reaction quotient and allows the accurate determination of equilibrium constants (including solubility constants).
