Question

If a current of 690.7 mA is passed through an electrochemical cell for 44.80 minutes, what charge, in coulombs, is passed through the cell?

Charge passed through the cell = coulombs

Suppose that the electrochemical cell consists of two copper electrodes immersed in a copper(II) sulfate solution. At which electrode, anode or cathode, does oxidationoccur?

The oxidation occurs at the

Do you expect that this electrode will increase or decrease in mass as the electrolysis proceeds?

The mass of the electrode will

Calculate the change in the mass of copper at the anode or cathode if the charge calculated above is passed through the cell described. Enter your answer as a positive quantity in mg.

Mass change at the electrode = mg
