2.4.3 Standard Hydrogen Electrode
The main idea is that the absolute potential of a single electrode cannot be measured. We can only measure the difference in potential between two electrodes. By choosing one electrode as a standard (the SHE) and assigning it a potential of 0.00 V, we can measure the relative potentials of all oth
