Brønsted -Lowery is different than Arrhenius because an acid or a base does not have to form a H+ or OH-ion. An acid has to donate a proton and a base has to accept a proton.

Sample Exercise 16.1 Identifying Conjugate Acids and Bases

The two bases in the equation are CO. 3 2–, the base in the forward reaction as written, and SO. 4 2– the conjugate base of HSO. 4 –. We can find the relative positions of these two bases in Figure 16.4 to determine which is the stronger base. Solve: CO. 3 2– appears lower in the right-hand column in Figure 16.4 and is therefore a ...
