For a science experiment you need to electroplate zinc onto both sides of a very thin, 1.00cm × 1.00cm copper sheet. You want the zinc thickness to be 140nm , and you know that the charge carriers in the ionic solution are divalent (charge 2e) zinc ions. The density of zinc is 7140kg/m3 .If the electroplating apparatus operates at 1.40mA , how long will it take the zinc to reach the desired thickness?
Perform the test and time how long it took – commonsense.
