Answer Details
The slope of the graph of the mass deposited against the quantity of electricity in Faraday's law of electrolysis gives the electrochemical equivalent. The electrochemical equivalent is a measure of the amount of substance produced by the passage of one coulomb of electricity through an electrolyte. In other words, it represents the amount of substance that is deposited or liberated at an electrode per unit charge passed through the electrolyte during electrolysis. Therefore, the correct option is "the electrochemical equivalent."
