A saturated hydrocarbon
An unsaturated hydrocarbon that contains at least one C=C double bond
A substance that can either accept or donate a proton to become an acid or a base
A substance that can act as either an acid or a base
The electrode where electrons exit the external wire and oxidation occurs
The amount of dissolved oxygen required to decompose organic material in water
A substance that can donate a proton
A substance that can accept a proton
A solution that is able to resist pH changes when small amounts of acid or base are added
The electrode where electrons enter the external wire and reduction occurs
The base that has accepted a proton and can now donate one

A table showing the standard electrode potentials for each reaction
The forcing of non-spontaneous reactions by applying a current of electricity
A conductive solution
A device that passes electricity from an external souce through an electrolyte to force non-spontaneous reactions to occur
A substance that is attracted to electrons
A reaction in which an electrophile reacts to swap ligands
An industrial method used to coat one metal with a thin layer of another metal using electrolysis
A metal in contact with an aqueous solution of its own ions
