Hi, can you tell me how much time I should let the reaction happen, to get Cl coated on only one electrode ( not excess to switch the terminals and re-run the reaction)??
As long as you run the current in one direction, you will be increasing the AgCl coating on one electrode. How long you run it depends on how much coating you want. For the lab in class, we plated at a rate of about 1mA/(cm)^2 and plated for a few minutes (each pair of partners did it differently), until they got a fairly uniform grey coating on the wires.
