how we can prove that z=E/96500also what is z here |
|
Answer» Z is a constant, known as "electro chemical equivalent" of the substance. If one ampere of current is passed for one second; then w = Z. This means when one ampere of current is passed for one second; then the weight or amount of the substance deposited or liberated is exactly equal to its electrochemical equivalent. The current in ampere, multiplied by the time in second is known as coulomb which is the electric charge.Electrochemical equivalent of a substance may be defined as the weight (amount) of the substance deposited or liberated, when one coulomb of electric charge is passed through an electrolyte. It is denoted by Z and in S.I unit it is expressed in Kg / coulomb. Each element has its own electrochemical equivale how to prove E/96500=z |
