Review Questions

• How did Michael Faraday's work on electromagnetic induction influence modern technologies?
  • Faraday's work on electromagnetic induction fundamentally changed our understanding of electricity and magnetism. By demonstrating that a changing magnetic field could induce an electric current, he paved the way for the development of electric generators and transformers. This principle is now at the core of many technologies, including power generation and electrical devices that rely on alternating current.
• Discuss how Faraday's Laws of Electrolysis contribute to our understanding of chemical reactions during electrolysis.
  • Faraday's Laws of Electrolysis provide a quantitative relationship between the amount of electric charge passed through an electrolyte and the amount of substance that undergoes a chemical change. The first law states that the mass of an element transformed at an electrode is proportional to the quantity of electricity passed. The second law establishes that this transformation is proportional to the equivalent weight of the substance. Together, these laws are crucial for predicting outcomes in electrochemical processes.
• Evaluate the long-term significance of Michael Faraday's contributions to science and industry, particularly regarding electrochemical processing.
  • The long-term significance of Michael Faraday's contributions extends far beyond his time, fundamentally shaping both scientific theory and industrial practice.
