c. In a separate electroplating experiment, if a 5.00 A current was used to electroplate a penny for 5.00 minutes, calculate how many grams of zinc will be plated on the penny. Note you would need to use the Faraday's constant, molar mass of zinc and cathode equation to answer this question. (2 marks)
Part A and B Please show all of the steps Analysis of Electroplating When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode. The amount of metal plated depends on the number of electrons passed. The total charge of a mole of electrons is...
