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.
