text: The 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
