Equivalent mass of copper

In the last few articles, we have studied the hydrogen displacement method, oxide formation method, reduction method, chloride formation method, and double displacement method to determine the equivalent mass of metal. The equivalent mass of a substance is the number of parts by mass of the substance which combines with or displaces or contains 1. If the equivalent mass is expressed in grams then it is called gram equivalent mass GEM. Thus the equivalent mass of chlorine is Equivalent mass has no unit because it is a pure ratio. The mass of any substance deposited or liberated or dissolved at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte. Example — On passing a current of 0. What is the equivalent mass of the metal? What is the equivalent mass of copper?
