Question

what will be the effect of increasing time for which current is passed on the amount of substance depositing​

Answer 1

Answer:

on increase time amount deposited at electrode is increased or amount that liberated is decrease

Answer 2

• The amount of substance deposited on a electrode surface increases with an increase in time.

• This can be explained using the Faraday's first law of electrolysis, i.e.

                              W = ZIt

                   where, W = weight of substance deposited

                                Z = electrochemical equivalent

                                I = current

                                t = time

• As W is directly proportional to t, therefore, as time increases the weight of the deposited substance increases.
