In the first part of this multiactivity lab, students determine the pH and buffer capacities of several buffer solutions they prepare. In the second part, students measure the pH of different aqueous salt solutions, write the net ionic equations that explain the pH, and use the pH values to calculate the K_a of an acidic ion and the K_b of a basic ion. This lab provides a meaningful review of the important properties of acid-base equilibria. Materials are sufficient for 30 students working in pairs. Materials needed, but not supplied, include fifteen 24-well microplates (item# 840723, pack of 12) and pH meters. *Kit complements the SAS inSchool Visual Library Software Series.
