Electrolysis of Aqueous Solutions

This is a lecture presentation on the electrolysis of aqueous solutions. The presenter explains what an aqueous solution is and what it contains, particularly aqueous solutions of metal salts. The presenter then presents a hypothesis on what happens when electrolysis is carried out on particular metal salts, and an assistant carries out experiments to test those hypotheses. The presenter goes on to explain the rules for deciding which ions will be discharged at each electrode and uses sodium chloride, copper chloride, and copper sulfate as examples to demonstrate the process. Safety precautions are also discussed throughout the presentation.
