Question

Take two conducting plates (10cm x 4cm), one of zinc and the other of copper. Take
250 ml of distilled water in a clean and dry beaker. Dissolve two table spoonful of copper sulphate in it. Add a few drops of dilute sulphuric acid (using appropriateprecautions) to make it more conductive. Connect the copper electrode to the positive terminal and the zinc electrode to the negative terminal of the battery. Allow a steady current to pass through this electrolyte for 20-30 minutes. Now, carefully take out the plates from the solution. What do we observe? Do we find a coating on one of the plates?
We will find a reddish copper coating on the zinc plate (cathode) connected to the negative terminal of the battery. It is copper,from copper sulphate solution,that has got deposited on this zinc electrode. We call this process of depositing a thin layer/coating of any desired metal on another metallic object ( by passing an electric Current) as electroplating.
Try repeating this activity using carbon/copper plates/rods as cathode. List your findings.​
