# Problem: One liter of a buffer from the blood is found to have 0.4 moles of acid (pK a = 4.76) and 0.1 moles of conjugate base. a. Is this pH of buffer greater than, equal to, or less than 4.76? Show your reasoning mathematically?   b. You want to get the buffer to maximum buffering capacity. You have HCl and NaOH available. Which would you add and how much in terms of moles? c. Is the pH of the buffer after step b greater than, equal to, or less than to 4.76?
