Chemistry-Chapter 18- Oxidation-Reduction Reactions and Electrochemistry
17
Oxidation Reduction Reaction: A chemical reaction involving the transfer of electrons.
Oxidation: A loss of electrons; an increase in oxidation state.
Reduction: A gain of electrons; a decrease in oxidation state.
Oxidation States: A concept that allows us to keep track of electrons in oxidation-reduction reactions.
Oxidizing Agent: A reactant that accepts electrons from another reactant; the oxidizing agent is reduced since it gains one or more electrons.
Reducing Agent: A reactant that donates electrons to another reactant; the reducing agent is oxidized since it donates one or more electrons.
Half Reactions: The two parts of an oxidation-reduction, one representing oxidation, the other reduction.
Electrochemistry: The study of the interchange of chemical and electrical energy.
Electrochemical Battery: Also known as a galvanic cell. This is a device in which chemical energy is converted to electrical energy by means of an oxidation-reduction reaction.
Anode: The electrode in a galvanic cell where oxidation occurs.
Cathode: The electrode in a galvanic cell where reduction occurs.
Electrolysis: A process that involves forcing a current through a cell to cause a chemical reaction that would not otherwise occur.
Lead Storage Battery: A battery used in cars in which the anode is lead, the cathode is lead coated with lead (IV) oxide, and the electrolyte is sulfuric acid.
Potential: The "Pressure" on electrons to flow from the anode to the cathode in a battery.
Dry Cell Battery: This is a battery that does not contain a liquid electrolyte; commonly used in calculators and watches.
Corrosion: The process by which metals are oxidized in the atmosphere.
Cathodic Protection: The connection of an active metal, such as magnesium, to steel to protect steel from corrosion.
