Question
The cathodic compartment of an electrolytic cell is 0.100 M in the ions Fe(CN63- and Cu2+ and has a chemically inert electrode. As current is passed through the cell, which best describes how Cu(s) is deposited on the electrode?
A.
Copper is deposited immediately, but at a rate much lower than 1 mol per 193000 C. As the electrolysis proceeds, the rate of copper deposition increases.
B.
Copper is deposited immediately, at a rate close to 1 mol per 193000 C. As the electrolysis proceeds, the rate of copper deposition decreases.
C.✓ Correct
No copper is deposited for a certain length of time, then copper deposition begins.
D.
Copper is deposited at a rate of 1 mol per 193000 C for a certain length of time, then the rate of copper deposition decreases.
