Using the same current and similar conditions, which will require the longest length of time?

Question

Quizplus · Accepted Answer

The time required for electrolysis is directly proportional to the number of moles of electrons transferred. In this case, depositing 0.20 mol of Cu from a Cu²⁺ solution requires the transfer of 0.40 mol of electrons, which is the most of all the options. Therefore, it will require the longest length of time.
