Electrolysis of Copper(II) Sulphate

Be analytic when study electrolysis of an aqueous solution.

3 factors affecting product of electrolysis  of an aqueous solution.

1. type of electrode
2. concentration of ion in aqueous solution
3. position of ion in the Electrochemical Series.

What factors are affecting product at anode & cathode during electrolysis of copper(II) sulphate solution?

Position of ion in the Electrochemical series

How do concentration & type of electrode affect product of electrolysis?

Arrangement of Atoms in Bronze

Orderly arrangement of copper atoms.

Presence of tin atoms with different size disrupt orderly arrangement of copper atoms. 
When a force is applied to bronze, the layers of copper atoms are not easily to slide over each other easily. Therefore, bronze is harder than copper.
