ARRENHIUS AND LOWRY & BRONSTEAD

Arrenhius

Said:

- Acids release HYDROGEN IONS when they are in water.

- Alkalis release HYDROXIDE IONS when they are in water.

However, these rules didnt work for all acids and alkalis. (the bases that do use this rule, are called alkalis.)

- even though it did work for many of them, he wasnt really listened to. Mainly because it was a brand NEW THEORY and he wasnt a very WELL KNOW scientist. Also, Ammonia neutralises acids but doesnt dissolve in water, which was something that other scientists used against him, and he couldnt explain. In addition, when Arrenhius first suggested that molecules ionise in water, scientists didnt believe him…
