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.

Answer rating: 100% (QA)

Solution 1 2 Since you havent mentioned pH of buffer solution We are going to calculate it by H2CO3 ... View the full answer
