Electrolysis of Water & Hydrochloric Acid

The video explores the concept of electrolysis, starting with its early discovery and the contributions of Michael Faraday, who named many of the terms used today. It discusses the equipment involved, such as anodes and cathodes, and the role of electrolytes. The video explains why pure water is a poor conductor and how adding sulfuric acid enhances electrolysis. It details the reactions at the electrodes, highlighting the redox process and the formation of gases in a 2:1 ratio. The video also examines how adding hydrochloric acid changes the reaction, producing chlorine instead of oxygen, and emphasizes safety precautions due to chlorine's toxicity.
