Question: 1) You have 50 mL of a buffer solution that is 0.15 M in HA and 0.25 M in A - . Calculate the pH

1) You have 50 mL of a buffer solution that is 0.15 M in HA and 0.25 M in A-. Calculate the pH of the solution after you add 100 mL of 0.01 M HCl to the solution. The pKa of HA is 4.75.


2)You wish to prepare 100 mL of a buffer solution that is 0.025 M in carbonic acid (H2CO3). The pKa of H2CO3 is 6.351. Calculate the amount of H2CO3, in grams, that you will need to weigh out.
