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.
In chemistry, a weak base is a chemical base that does not ionize fully in an aqueous solution. As BroenstedâBrÃ¸nsted lowry bases are proton, acceptors a weak base may also be defined as a chemical base in which protonation is. Incomplete this results in a relatively pH ph compared to strong. bases
