On This Day In Chemistry

May 2nd

William Nicholson became the first man to produce a chemical reaction by electricity on this day in 1800

The English chemist discovered that when leads from a battery are placed in water (H2O), the water breaks up into hydrogen (H2) and oxygen (O2) bubbles, which collect separately at the submerged ends of the wires. This process is called electrolysis.
