Electrochemistry is a sub-discipline within the
field of physical chemistry. Its attention is directed
primarily to all those processes where
chemical reactions involve the migration of electrical
charges or the generation of electrical
potentials.
Physics is concerned with current as electrons
move within solid conductors (metals, 1st-order
conductors). Of special interest for the field of
microelectronics is the differing response of the
semiconductors. Also the unexpected, rapid
advances in the field of superconductors implying
low-loss transmission of electrical energy
give reason to anticipate new and spectacular
applications in the future.
In contrast to the science of physics, chemistry

focuses on the transmission of electrical
charges by means of ion migration in electrolytes,
the so-called “2nd-order conductors“.
Electrochemistry first examines the parameters
which determine the electrical conductivity
of solutions: the type of material, the concentration,
the degree of dissociation, ion migration
speed, etc.
One of the main chapters in the study of electrochemistry
is the determination of the electrochemical
potentials of various galvanic cells,
right down to the fundamental realization that
every reduction oxidation system can be assigned
a certain standard potential. This makes it

possible to set up an electrochemical series of
elements and compounds, giving essential information
as to their inert or active properties and
to their strength as oxidation or reduction
agents. Application of this knowledge leads to
various galvanic elements, such as the Leclanché
cells, the lead accumulator battery, etc.
The situation in the case of electrolysis, and its
application in galvanizing, for example, or in
copper refining, anodizing and the electrolysis of
alkali metal chlorides, is just the reverse. Here a
chemical reaction is initiated by the application
of electrical energy. Corrosion and corrosion
protection also involve electrochemical
processes.
