Electrochemistry - introduction
2018/6/22· Electrode reactions take place within the double layer, and when they do so, they alter the potential difference across this interfacial region. Much of the importance of electrochemistry lies in the fact that by applying an external voltage to the electrode, we can control both the direction and rate of an electrode reaction.
