Question

The mass of the element deposited at the electrode when one coulomb of charge is passed through the electrolyte is called __________ of the element.

• A. mass equivalent
• B. charge equivalent
• C. electrochemical equivalent
• D. resistivity

Answer 1

Answer: (C)

electrochemical equivalent

Electrochemical equivalent of an element is defined as the weight of the element deposited or evolved during electrolysis by the passage of a specified quantity of electricity and usually expressed in grams per coulomb, the value for silver as the usual standard being 0.001118 gram/coulomb which means with the flow of 1C charge 0.001118 gm of silver gets deposited.
Element Electrochemical equivalent of Copper is 0.0003281 grams/ coulomb.
