Question

Difference between chemical equivalent and electrochemical equivalent

Answer 1

Chemical equivalent and electrochemical equivalent are entirely different things in chemistry. Here is what the two mean: 

Chemical equivalent : 

Chemical equivalent of an element is the value obtained by dividing the atomic weight of the given element by its valency.

Electrochemical equivalent:

Electrochemical equivalent  on the other hand, refers to the mass of substance deposited when a current of 1 Ampere is passed for 1 Second during electrolysis. (or the mass of a substance deposited when 1 coulomb of electricity is passed through). 

Answer 2

Electro-chemical equivalent is the ratio between chemical equivalent weight and the Faraday number it's representation formula is ECE= E/F. it is that mass of the substance due to passage of 1 coulomb deposited or removed by the process of electrolysis.
while the chemical equivalent is the weight of the one gram of substance that can combines with or displace with 1 g of the hydrogen . Formula weight/valency is the chemical formula .
