16. Which of the following statements does NOT correctly describe buffer capacity? a. Buffer capacity is determined only by the identity of the buffer. b. The addition of amounts of acid or base exceeding the buffer capacity will change the pH of the solution. c. The higher the concentration of weak acid and conjugate base in solution, the higher the buffer capacity. d. The greatest amount of acid or base that a buffer can accept while maintaining pH is called the buffer capacity. e. Once the buffer capacity is exceeded in cells, key functions of the body can be disrupted.
