What mass of copper could be electroplated on the cathode in an experiment were an average of 200 mA was passed through the cell for 35 minutes?
Expert Answer
Charge passing through the cell is determined using the given formula.
Equation for the electrolysis of copper is given below. 2 moles of electron are needed to form 1 mole of copper. Hence each mole of Cu requires 19300 C (2×96500 C). therefore, number of Cu formed by 420 C is determined.
Mass of copper deposited is ...
