the conversion of chemical energy into electrical energy or electrical energy into chemical energy; all electrochemical processes involve redox reactions
Any device that converts chemical energy into electrical energy or electrical energy into chemical energy
An electrochemical cell used to convert chemical energy into electrical energy; the energy is produced by a spontaneous redox reaction
the part of a voltaic cell in which either oxidation or reduction occurs; it consists of a single electrode immersed in a solution of its ions
a tube containing a strong electrolyte used to separate the half-cells in a voltaic cell; it allows the passage of ions from one half-cell to the other but prevents the solutions from mixing completely
a commercial voltaic cell in which the electrolyte is a moist paste. Example - Flashlight batteries
a voltaic cell that does not need to be recharged; the fuel is oxidized to produce a continuous supply of electrical energy
a measure of the tendency of a given half-reaction to occur as a reduction (gain of electrons) in an electrochemical cell
Standard Cell Potential
The measured cell potential when an ion concentration in the half cells are 1.00M at 1ATM of pressure and 25C. (E cell)
Standard Hydrogen Electrode
An arbitrary reference electrode (half-cell) used with another electrode (half-cell) to measure the standard reduction potential of that cell; the standard reduction potential of a hydrogen electrode is assigned a value of 0.00V
A process in which electrical energy is used to bring about a chemical change; the electrolysis of water produces hydrogen and oxygen
