Question

Copper sulfate solution was electrolysed using copper electrodes. Before the electrolysis, the masses of the electrodes were determined.After the electrolysis, the electrodes were washed and dried and their masses re-determined. Figure 6 shows these masses and the resulting changes in masses of the electrodes. Explain these results.(4)

Answer 1

Answer:

mass changes because during the process of electrolysis copper electrode connected to positive terminal will give some copper particles to copper sulfate solution and the electrode connected to negative terminal will gain the copper particles from the solution that's why the masses changes
