Galvanic Cells: Standard Potentials and Concentration Effects

This lecture covers the determination of the voltage of a galvanic cell by calculating the difference in standard potentials of each electrode. It explains the relationship between standard reduction potentials and the electromotive force, as well as the impact of concentrations on cell voltage. The lecture delves into the concept of equilibrium constants, free energy, and the spontaneity of redox reactions. Practical examples are provided to illustrate the calculations involved in non-standard conditions and concentration cells. Additionally, the lecture explores the use of pH meters in concentration cells and concludes with an exercise on determining the solubility product of a compound.
