Describe how buffers will adjust pH of a solution very slightly. Discuss why a buffered solution is resistant to change in the pH when an acid or base is added. Define a buffer in terms of added acid and conjugate base formation. Introduce a buffer problem: What is the pH of a solution that contains a given molarity of acetic acid and a given molarity of sodium acetate. Work through the problem completely, include the formation of an ICE table and derivation of the pH based on the new pH of the solution
