Suppose you have created a butter solution that is 0.250 M in both benzoic acid (HC,H,O,) and potassium benzoate (KCH,0z) and that the pH of this solution is 465. Assuming that the butter capacity has not been exceeded, which of the pH values listed below would you expect after adding a small amount of a dilute strong acid solution?

A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 mL solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O,. The initial concentration of both the acid and the base are 0.0100 mol/ 0.1000 L...
