Arrhenius sticks to the basics

Svante Arrhenius was a Swedish chemist who is credited not only with the acid-base determination method that s named for him but also with an even more fundcimental chemical concept that of dissociation. In his PhD thesis, Arrhenius proposed an explanation for a phenomenon that, at the time, had chemists all over the world scratching their heads. What had them perplexed was this Although neither pure salt nor pure water is a good conductor of electricity, solutions in which salts are dissolved in water tend to be excellent conductors of electricity. 

Arrhenius subsequently expanded his theories to form one of the most widely used and straightforward definitions of acids and bases. Arrhenius said that acids are substances that form hydrogen (H+) ions when they dissociate in water, while bases cire substances that form hydroxide (OH ) ions when they dissociate in water. 

Peruse Table 16-1 for a list of common acids and bases, noting that all the acids in the list contain a hydrogen at the beginnings of their formulas and that most of the bases contain a hydroxide. The Arrhenius definition of acids and bases is straightforward and works for many common acids and bases, but it s limited by its narrow definition of bases.
