Buffers

At the end of this activity, students should be able to:
– define acidic and alkaline buffers
– describe quantitatively how buffers work
– calculate the pH of a buffer solution
– calculate the pH changes resulting from the addition of strong acids/bases to buffer solutions
– determine the pH range of a buffer based on Ka and Kb constants
– calculate the amounts of acid/base and salt required to prepare a buffer solution of specified pH.
