IB SL Chemistry Redox Vocab
Terms in this set (17)
Loss of electrons; increase in oxidation number
Gain of electrons; decrease in oxidation number
Reaction in which oxidation and reduction occur; process by which one or more electrons are transferred
A positive or negative number that indicates the degree of electron control; used to keep track of electrons in a redox reaction
An equation that shows only oxidation (or only reduction); the sum of the two half equations results in the overall balanced equation (where all the electrons cancel out)
The reactant that contains the species being reduced; causes the other reactant to be oxidized
The reactant that contains the species being oxidized; causes the other reactant to be reduced
The application of redox reactions (flow of electrons); two main types are voltaic cells and electrolytic cells.
Made of two half cells, each of which is made of a metal in a solution of its ions. The two half cells are connected via a salt bridge and an external circuit. Generates a flow of electrons from a spontaneous chemical reaction.
Made of one cell, with two inert electrodes in an electrolyte. A battery pushes (forces) electrons through to create an non-spontaneous chemical reaction.
An electrode in an electrolyte where either oxidation or reduction occurs
Where electric current enters and leaves the electrolyte. Usually made from a metal in an electrolyte. Anode or cathode.
Electrode where oxidation occurs
Electrode where reduction occurs
A connection between two half cells in a voltaic cell that completes the circuit and allows current to flow by preventing charge build up. Usually made of a glass tube containing ions that will not interfere with the chemical reaction.
An ionic compound that conducts electricity when melted or solid
