75mL of a 0.2M solution of the tripeptide Ser-Cys-His is adjusted to pH=8.6. The solution is then titrated with 50mL of a 0.5M HCl. Calculate the new pH value of the tripeptide solution. (Relevant pKa values are: 2.2, 6.0 8.3, and 9.6). Once you've completed the addition of HCl to the tripeptide in part A, then you titrate the solution with 30mL of 0.6M NaOH. Calculate the final pH value of the tripeptide solution.

You are conducting a biochemical experiment with an enzyme that has optimal activity at pH = 10.50. You decide to use carbonate (pKa1 = 6.38, pKa2 = 10.30) as the buffer to keep the pH stable throughout the enzymatic reaction. (Recall that the formula for carbonic acid is H2CO3.) You prepare a 0.6 M solution of carbonate buffer at pH = 10.50. Calculate the concentrations of the major carbonate species in your solution. Show your calculations.
