Homework Solutions for Raymond Chang’s Chemistry (9 th Edition) Chapter 15: Acids and Bases 15.1 Brønsted Acid: A compound which is a proton donor Brønsted Base: A compound which is a proton acceptor A conjugate pair is made up of either a Brønsted acid and its conjugate base (CB) or a Brønsted base and its conjugate acid (CA). The conjugate base of a Brønsted acid is the compound which results from the loss of the acid’s most acidic proton. The conjugate acid of a Brønsted base is the compound which results by addition of one proton to the base. Some examples of conjugate acid/base pairs and their reactions are as follows: 15.2 Brønsted bases must have a lone pair with which to accept a proton. These electrons are necessary to form the bond between the base and the proton. 15.3 (a) H 2 O: both—Water has both protons to donate and electron pairs with which to accept protons. Example auto-ionization of water (see above). (b) OH - : base (c) H 3 O + : acid (d) NH 3 : base—can accept a proton and doesn’t act as an acid since its conjugate base NH 2 - is a very strong base. (e) NH
