In Faradays law of electrolysis; a graph of the mass deposited against the quantity of electricity is plotted. The slope of the graph gives?

A. the energy released
B. the electrochemical equivalent
C. the current flowing
D. the charge released

Correct Answer:

Option B – the electrochemical equivalent

Explanation

In Faraday’s law of electrolysis
M = It = Q
Where M is the mass of substance deposit. Q is the quantity of charge. A graph of m against Q is a straight line passing through the origin with slope equal to the electrochemical equivalent. Z
