I need help with some lab questions for the Electrolysis and Electroplating Lab:
1.) Find the
actual mass of metal plated out for Cu/Cu cell and Zn/Zn cell.
2.) Find the Coulomb passed during the reaction for Cu/Cu cell and Zn/Zn cell.
3.) Find the theoretical mass of metal plated out for Cu/Cu cell and Zn/Zn cell.

Solution is turning dark , bubbling. Turning into

see through the mixture. Black precipitate at the
Solution is also turning Kind of dark. Metal is
turning ved. Still, the same blue color, except its
