Electrochemistry
Electrochemistry is the study of chemical changes produced by electric current and with the production of electricity by chemical reactions. All electrochemical reactions are redox reactions, which means that electrons are always transferred. Most electrochemical reactions occur in cells. Cells are contained places for reactions where electricity enters and exits through electrodes. There are two main types of cells. One type, the electrolytic cells, requires electricity to produce a non-spontaneous chemical reaction. The other type, …showed first 75 words of 404 total…

…showed last 75 words of 404 total…If the two electrodes are connected through a wire, the more reactive metal electrode between the half-cells would begin to dissolve while the salt solution in the other half-cell would begin to plate out onto the electrode. The electricity produced by this cell would depend solely upon the reactivity of metals used in the reactions. The reactivity of metals are determined by the voltage they produce when oxidized as compared to the standard hydrogen half-cell.
