In the equation \(m=Z Q . Z\) represents ____________
A. gravitational constant B. partial constant C. electrode constant D. electrochemical equivalent
Correct Answer: D
Explanation
The equation \(M=Z Q\) is from Faraday's first law of electrolysis. "The mass of an element produced during electrolysis is directly proportional to the quantity of electricity passing through the electrolyte" \(Z\), the constant of the proportionality is known as the electrochemical equivalent of the element. The electrochemical equivalent, \(Z\) is the mass of the element that will be produced when the quantity \(Q\) of electricity passing through the electrolyte is one coulomb.
