Electrolysis of Aqueous Copper Sulfates: Analysis and Conclusion

The video is a lecture presentation on the electrolysis of aqueous copper sulfates. The presenter discusses an experiment to test the hypothesis about the relationship between the current through the electrolyte and the mass of copper deposited on the cathode. The experiment involved using copper electrodes connected to a variable power supply and an ammeter, and placing them in a beaker of copper sulfate solution. The results are analyzed and presented in a table and graph format, where it is observed that the change in mass of the cathode does increase with an increase in current, and that this relationship is proportional. It is also noted that the change in mass of the anode is negative, but the mass of copper deposits on the cathode is equal to the mass of copper lost by the anode, based on the results. The video concludes with a summary of the experiment and its findings.
