Electrochemistry is about "Electron Traffic Control."

'''The Redox Rule (OIL RIG)''':
* '''O'''xidation '''I'''s '''L'''oss (of electrons).
* '''R'''eduction '''I'''s '''G'''ain (of electrons).
You cannot have one without the other. If one atom gives up an electron, another must take it.

'''Batteries vs. Electrolysis''':
* '''Batteries (Galvanic)''': You have two chemicals that ''want'' to trade electrons. You separate them and force the electrons to travel through a wire (a circuit) to get to the other side. That flow of electrons ''is'' the electricity we use.
* '''Electrolysis (Electrolytic)''': You have a chemical (like water) that is stable. You use a battery to ''force'' electricity into the water, breaking its bonds and turning it into Hydrogen and Oxygen gas.

'''The Nernst Equation''': This is the fundamental equation of electrochemistry. It relates the cell potential (voltage) to the concentration of the chemicals. This explains why your phone battery's voltage drops as it dies—as the "fuel" is used up, the chemical pressure (potential) decreases.
