The correct answer is Discovery of water electrolysis

Key Points

  • Discovery of water electrolysis was a significant experimental achievement made by William Nicholson in 1800.
  • This discovery involved the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) through the application of electric current.
  • It was a foundational experiment in the field of electrochemistry and demonstrated the potential of electricity to induce chemical reactions.
  • Nicholson's work laid the groundwork for further scientific exploration and technological advancements involving electrolysis.

Additional Information

  • William Nicholson was an English chemist and inventor who made significant contributions to the field of science in the late 18th and early 19th centuries.
  • The process of water electrolysis is now widely used in various industrial applications, including the production of hydrogen fuel.
  • Electrolysis is also employed in the extraction of metals from their ores and in electroplating processes.
  • The discovery of water electrolysis marked a pivotal moment in the understanding of the relationship between electricity and chemical reactions.
