Electrochemistry is the branch of chemistry that studies the relationship between electrical energy and chemical change. Key concepts include: Oxidation-reduction (redox) reactions*: Reactions where electrons are transferred between species. Oxidation is the loss of electrons, and reduction is the gain of electrons. Electrochemical cells*: Devices that convert chemical energy into electrical energy (galvanic/voltaic cells) or use electrical energy to drive non-spontaneous chemical reactions (electrolytic cells). Electrodes: Conductors where oxidation and reduction occur. The anode is where oxidation happens, and the cathode* is where reduction happens. Electrolytes*: Solutions or molten salts that contain ions and can conduct electricity. Standard electrode potentials*: The potential difference of a half-cell under standard conditions (1 M concentration, 1 atm pressure, 25°C). These are used to calculate the overall cell potential. Faraday's laws of electrolysis*: Quantify the relationship between the amount of substance produced or consumed at an electrode and the quantity of electricity passed.
