Copper can be electroplated at the cathode of an electrolysis cell by the half-reaction. Cu2+(aq)+2e−→Cu(s) How much time would it take for 329 mg of copper to be plated at a current of 7.1 A ? Express your answer using two significant figures.
Copper can be electroplated at the cathode of an electrolysis cell by the half-reaction: Cu2+(aq)+2e−→Cu(s) How much time would it take for 348 mgmg of copper to be plated at a current of 6.3 AA?
What is the reduction half-reaction? In the electrolytic cell of this experiment, copper metal is the anode and zinc metal the cathode. The electrolyte solution is sulfuric acid, H2SO4. Oxidation occurs at the copper anode, where Cu is oxidized to Cu^2+: Cu (s) → Cu^2+ (aq) + 2 e– During the experiment, you might have noticed that at the end of the trials, the solution becomes slightly blue, which proves the existence of aqueous Cu^2+. What is the reduction half-reaction...
