Electrochemical equivalent is defined in the context of the calculation of the current density of electrodeposition of alloys. In order to calculate the current efficiency of the alloy deposition process, it is necessary to know the mass of the alloy expected to be deposited per Faraday of electricity when no other electrode reaction than the alloy deposition occurs at the electrode surface. Since alloys do not have a faxed composition, in other words, since alloys do not obey the law of definite properties, it is not possible to calculate theoretically the mass of the alloy deposited per Faraday. Thus there exists no fixed value for the electrochemical equivalent of an alloy. However, the current efficiency for an alloy deposition process can easily be calculated, without any need to know or define the electrochemical equivalent of an aUoy. An analysis of the alloy deposited can be obtained experimentally and the corresponding Faradays utilised can be calculated. The ratio of this quantity to the number of Faradays passed through the cell would give the current efficiency for the alloy deposition process. The above a..<;pects are dealt with in detail in the paper.
