Question

In electrolysis, the amount of mass deposited or liberated at an electrode is directly proportional to:

• A. amount of charge
• B. square of current
• C. concentration of electrolyte
• D. square of electric charge

Answer 1

Answer: (A)

amount of charge

Using the relation $[m=Z\times i\times t]$
where Z is its electrochemical equivalent , i is current , t is time and m is the mass deposited or liberated .
Amount of mass deposited or liberated at an electrode is directly proportional to amount of charge.
