Question- Calculate the quantity indicated for each of the following electrolyses. Enter scientific notation as 1.23E4. (a) [Cu2+] remaining in 442 mL of a solution that was originally 0.893 M CuSO4, after passage of 3.09 A for 499 s and the deposition of Cu at the cathode.
(Note: 1 A = 1 C s^-1)
(b) The time required to reduce [Ag+] in 169 mL of AgNO3(aq) from 0.196 to 0.106M by electrolyzing the solution between Pt electrodes with a current of 3.90 A. (Note: 1 A = 1 C s-1)
Solve the above problem and provide steps with explanation
