In chemistry, the electrochemical equivalent (Eq or Z) of a chemical element is the mass of that element (in grams) transported by a specific quantity of electricity, usually expressed in grams per coulomb of electric charge.[1] The electrochemical equivalent of an element is measured with a voltameter.
Definition
editThe electrochemical equivalent of a substance is the mass of the substance deposited to one of the electrodes when a current of 1 ampere is passed for 1 second, i.e. a quantity of electricity of one coulomb is passed.
The formula for finding electrochemical equivalent is as follows:
where is the mass of substance and
is the charge passed. Since
, where
is the current applied and
is time, we also have
Eq values of some elements in kg/C
