A positive or negative integer assigned to a compound, representing the total electrons it as gained/lost when it formed bonds

The loss of electrons by a molecule, atom, or ion, during a reaction

A process involving the gain of electrons by a substance, which decreases its oxidation number

chemical processes involving the transfer of electrons between two species, resulting in a change in oxidation states

substance that causes oxidation by accepting electrons from another substance in a redox reaction, becoming reduced in the process.

a substance in a redox reaction that donates electrons to another species, causing that species to be reduced while the reducing agent itself becomes oxidized

galvanic/voltaic cell

The experimental apparatus for generating electricity through the use of a spontaneous reaction

The electrode at which the oxidation occurs

The electrode at which the reaction occurs

Cell potential, the voltage across the electrodes of a galvanic cell. Also known as electromotive force (emf), which measures voltage

standard reduction potentials

Voltage associated with a reduction reaction at an electrode when all solutes are 1 M and gasses are 1 atm

The oxidation and reduction reactions at the electrodes

An apparatus for carrying out electrolysis

Branch of chemistry that deals with the interconversion of electrical energy and chemical enegry

an electrolytic process that uses electrical current to reduce dissolved metal ions, depositing a thin, coherent layer of metal onto a conductive surface

connects two half-cells, maintaining electrical neutrality and completing the circuit

a typographical method of expressing a chemical structure as a linear string of printable characters

a fundamental electrochemical formula that relates the reduction potential of an electrochemical reaction (half-cell or full cell) to the standard electrode potential, temperature, and activities (concentrations) of the chemical species

Process at which the electrical energy is used to cause a non spontaneous chemical reaction to occur

A galvanic cell or a series of them that can be used as a source of direct electric current at a constant voltage
