Typically, when a buffer is made in the laboratory, the solutions of the weak acid and the salt of the conjugate base are mixed and adjusted to the correct pH using a strong acid or a strong base. Using each of HCl and NaOH as examples, respectively, explain how the strong acid or strong base react in solution (what ions are created) and how they react with the buffer components to change the pH. Use the following as your representative buffer: \ce{H2PO4- (aq) <--> H (aq) HPO4^2-}
