JOHANNES BRONSTED (1879-1947) THOMAS LOWRY (1874-1936)

1923 – Denmark

‘An acid is a molecule or ion capable of donating a proton ( a hydrogen nucleus, H+ ) in a chemical reaction, while a base is a molecule or ion capable of accepting one’

The Bronsted-Lowry concept extends Arrhenius’ concept as it includes reactions that take place in the absence of water.

The strongest known acid is an 80 percent solution of antimony pentaflouride in hydrofluoric acid.
The strongest known base is caesium hydroxide.
