Acids and Bases - Lewis Definition Of Acids And Bases. The BrÃ¸nsted-Lowry acid-base definition, while broader than the Arrhenius definition, is still limited to hydrogen-containing compounds, and is dependent on a hydrogen ion (that is, a proton) transferring from one molecule to another.
Acid = substance containing hydrogen which gives free hydrogen (H + ) when dissolved in water. Base = substance containing the OH group that yields free (OH - ) when dissolved in water. An acid solution is one containing an excess of free H + , and a base is one containing excess of free OH - .
