On This Day - May 02: Nicholson split water

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.

On This Day – Sep 02 : Friedrich Ostwald was born

He was one of the founders of classical physical chemistry. In particular, Ostwald was a pioneer of electrochemistry and chemical dynamics. He won the Nobel Prize for Chemistry in 1909 for his work on catalysis, chemical equilibrium, and reaction velocities.
