1) Zinc metal is deposited onto a cathode surface by passing a current of 1.87 amps through a solution of Zn2 for 42.5 minutes. Calculate the mass of zinc (in grams) deposited in this time. 4 pts)
Metal plating is done by passing current through a metal solution. For example, an item can become gold plated by attaching the item to a power source and submerging it into a Au3+ solution. The item itself serves as the cathode, at which the Au3+ ions are reduced to Au(s). A piece of solid gold is used as the anode and is also connected to the power source, thus completing the circuit. What mass of gold is produced when 20.0...
