Question:
(A) If 12.3 g of Cu is deposited at the cathode of an electrolytic cell after 5.50 h, what was the current used?
(B) For how long would the electrolysis in Example 19-13 have to be carried out, using Pt electrodes and a current of 2.13 A, to produce 2.62 L O2(g) at 26.2 °C and 738 mmHg pressure at the anode?
Example 19-13
The electrodeposition of copper can be used to determine the copper content of a sample. The sample is dissolved to produce Cu2+(aq), which is electrolyzed. At the cathode, the reduction half-cell reaction is Cu2+(aq) + 2 e- → Cu(s). What mass of copper can be deposited in 1.00 hour by a current of 1.62 A?
