A- What is the pH of a buffer prepared by adding 0.809mol of the weak acid HA to 0.305mol of NaA in 2.00L of solution? The dissociation constant Ka of HA is 5.66 X 10^-7 B- What is the pH after 0.150mol of HCL is added to the buffer from Part A? Assume no volume change on the addition of the acid. C- What is the pH after 0.195mol of NaOH is added to the buffer from Part A? Assume no volume change on the addition of the base. Please give all answers to 3 decimal places.
