The electrolysis of copper sulphate solution and copper electrodes

Introduction:

For my GCSE Chemistry assessment I will be investigating the
electrolysis of copper sulphate solution with the copper (ii) plates.

Aim:

My intention for this observation is to find out how the current has
an effect on the mass of copper deposited in the electrolysis of
copper sulphate and copper (ii) plates.

Safety Precautions:

In this investigation I will make sure that everything is as safe as
possible and that there are no chances of accidents occurring.

(1) I will wear safety glasses and a lab coat to avoid any danger.

(2) I will tie my hair back, which will prevent any accidents from
occurring.

(3) I will keep the area around me clear to prevent any accidents from
occurring.

(4) Benches should be tucked under the table so that nobody trips
over.

(5) As copper sulphate indicates the symbol, which means toxic, I will
be careful that it is kept away from my skin and I am not able to
smell it. The reason for this is that it can cause death.

(6) Copper sulphate will be pla...

substance discharged at an electrode.

This law infant matches my results that I have gained, I can now
confidently say that the results that I obtained were accurate. As I
increased the voltage and the current there was a larger mass in the
cathode. Therefore this proves that my prediction which I made is
correct:

As the current increases the amount of copper deposited will also
increase.

In this electrolysis both the oxidation and reduction reactions have
been used, the oxidation in the anode and the reduction in the
cathode.
