An oligopeptide with the sequence A-P-C-K-R was obtained from blood plasma.
a) How many moles of NaOH would be required to titrate one mole of the fully protonated peptide to its fully unprotonated form? 5
b) If you had 100 ml of a 1.00 M solution of the fully unprotonated form of this peptide, what would the pH be?Answer: pH = 13.25.
Please explain how the instructor got the answer of pH 13.25
