Unit 10: Acid-Base Theories - SHS Chemistry.

There is a whole new definition of acid-base behaviour that you are just about to meet (the Lewis theory) which doesn't necessarily involve hydrogen ions at all. A Lewis acid is an electron pair acceptor; a Lewis base is an electron pair donor (see below).

W., Australia The theory of acids and bases, like many other chemical theories, has undergone numerous changes in recent times. Always the changes have been such as to make the theory more general. The three main theories in use today are.

Arrhenius theory, theory, introduced in 1887 by the Swedish scientist Svante Arrhenius, that acids are substances that dissociate in water to yield electrically charged atoms or molecules, called ions, one of which is a hydrogen ion, and that bases ionize in water to yield hydroxide ions.

Acids and bases are two groups of chemical compounds with opposite properties that are encountered frequently in the laboratory and in everyday life. Acids, bases, and the products of their reactions are vital to many life processes and are invaluable to industry and agriculture. Acids generally taste sour or tart.
