Does increasing concentration of copper sulfate decrease or
Does increasing concentration of copper sulfate decrease or

My hypothesis was that as the concentration is increased, so will the rate of electrolysis. However, my results are completely opposite. When I use 0.1 M solution, loads of copper is deposited on the cathode but as I increase the concentration, the amount of copper deposited becomes progressively less and less.

Additionally, the copper sulfate electrolyte solution contains copper in the form of positivelycharged cations, which are also attracted to the negative electrode (the cathode, a dime). This results in the net loss of copper from the anode (penny) and the gain of a copper coating on the cathode (dime).

When in solution, the ions are free to move and can carry an electric charge. Ions are also produced from the water: H2O (l) >H+(aq) + OH (aq) CuSO4 (aq) >Cu2+(aq) + SO42 (aq) The copper ions carry a positive charge and are attracted to the cathode. In the electrolysis of copper sulphate a number of things happen at the anode.
