If 1.70 liters of 0.670 M CuSO4 solution is electrolyzed by passing 4.70 amps through the solution for 3.00 hr using inert electrodes.
(a) As electrolysis proceeds, how does the acidity of the solution change?
(b) How many grams of Cu metal are formed at the cathode?
(c) How many liters of oxygen gas are collected at 29.5°C and 730. mm Hg?
(d) What is the [Cu2+] in the solution at the end of the electrolysis?
