General Chemistry Laboratory/Acids and Bases

Acids and bases are two classes of chemical molecules that interact in a particular way with each other when combined. There are multiple definitions of acid and base molecules. One of the most common of these is the Brønsted-Lowry definition, which indicates that an acid is a proton donor, while a base is a proton acceptor. Another common definition is the Lewis definition, which indicates that an acid is an electron acceptor, while a base is an electron donor. Acids Monoprotic acids involving hydrogen, per the Brønsted-Lowry definition, contain two bonded molecules - hydrogen and another - in a one-to-one ratio.
