Neco Model Questions Vol1 2017 Chemistry Question 28
Practice objective / multiple choice question 28 from the 2017 Neco Model Questions Vol1 Chemistry examination.
An electrolytic cell contains 0.050 mol of \(\text{Zn}^{2+}\) and 0.030 mol of \(\text{Cu}^{2+}\) in 500 mL solution. A constant current of 2.00 A is passed for 3.00 h. The cathode is a copper strip and the anode is zinc metal. Because of over‑potential only 85 % of the current contributes to the intended metal deposition/dissolution reactions. (a) Calculate the mass of copper deposited on the cathode. (b) Calculate the mass of zinc that dissolves at the anode.
