Electrochemistry Exercises Resolution

This lecture covers the resolution of electrochemistry exercises, focusing on calculating acidity constants, pH values, and understanding the reactions at the electrodes in a cell made up of hydrogen half-cells. The instructor explains how to determine the polarity of electrodes, the direction of reactions during charging and discharging, and the relationship between pH levels in different compartments. Emphasis is placed on calculating potential differences, concentrations of redox species, and the importance of balancing spontaneous reactions in concentration piles.
