1. Electrolytic reactions, like other chemical reactions, arenot 100% efficient. In a copper purification apparatus depositingCu from a CuSO4 solution, operation for 5.47 hours at a constantcurrent of 5.45 A deposits 29.2 g of Cu metal. What is theefficiency?
b) How long would it take to electroplate all theZn2+ in 0.280 L of 0.210 M ZnSO4 solutionwith a current of 2.35 A?
please answer both A and B
