Voltaic Cells 1
a device that converts chemical energy into electrical energy or electrical energy into chemical energy
What is an electrochemical cell?
electrode at which oxidation takes place
What is the anode?
the loss of metal resulting from an oxidation-reduction reaction of the metal with substances in the environment
Corrosion
the loss of metal due to a redox reaction of the metal with substances in the environment
What is Corrosion?
the use of electrical energy to cause a chemical reaction
What is Electrolysis?
Depend on reversible redox reactions and are rechargeable
Secondary batteries
electrode at which reduction takes place
What is the Cathode?
the coating of iron with a layer of zinc
What is Galvanizing?
A voltaic cell in which the oxidation of a fuel is used to produce electric energy
Fuel cell
the tendency of an electrode to gain electrons
What is Reduction potential?
produce electric energy by means of redox reactions that are not easily reversed.
What is a primary battery?
Produces electric energy by means of redox reactions that are not easily reversed
Primary battery
These depend on reversible redox reactions and are rechargeable.
What is a secondary battery?
the voltage measured between the electrode of a half-cell and the standard hydrogen electrode
standard reduction potential
the term for one or more voltaic cells in a single package that generates electric current
