Electrolorimetry Lab Report

Title: An investigation on the effect of a change of concentration of the electrolyte to the amount of the layer of Copper deposited in an iron object (iron spoon) in an electroplating process

Aim:

A.) To electroplate an Iron object (iron spoon) with copper through the electrolysis of a Copper (II) sulfate solution and by using copper anode

B.) To measure the amount of the copper that is plated on the iron spoon after the process of electroplating in a certain amount of time

C.) To measure the differences to the amount of copper plated on the iron object after using an electrolyte of different concentration in a certain amount of time

Background of the study:

Electroplating is a process of coating a metal object with a thin layer of another

9.) Take the plated iron spoon and dry using the paper towel

10.) Take the weight of the plated iron spoon out and record the results

Repeat the experiment using the electrolyte of Copper (II) sulfate with 1 mol/dm3 concenctration

1.) Fill another beaker with 100ml Copper (II) sulfate solution at 1 mol/dm3 concentration

2.) With the alligator clips, attach one copper strip to a wire.

3.) Connect one of the wires attached to the copper strips to the positive electrical output of the power pack

4.) Attach another alligator clip to an iron spoon and connect the wire to the negative electrical output of the power pack

5.) Place in both iron spoon and copper strip in to the electrolyte. Do not allow the copper strip and the spoon to come in contact

6.) Switch on the power pack at 4 volts. Let it run for three minutes.

7.) After three minutes, switch off the power pack.

8.) Take the plated iron spoon out and dry using the paper towel

9.) Take the weight of the plated iron spoon and record the results

Repeat the experiment using the electrolyte of Copper (II) sulfate with 1.5 mol/dm3 concenctration

1.) Fill another beaker with 100ml Copper (II) sulfate solution at 1.5 mol/dm3
