Based on pKas of glycine hydrochloride estimate the percentage of molecules that are fully protonated in a solution with pH = 4.4

pKa1 = 2.35 ,pKa2 = 9.60 , MW = 111.6

Solutions

Expert Solution

  • Chloride ion being of no importance here, has been omitted.
  • It can be seen from the pKa values that the first proton will be lost from COOH group. So we shall do all calculations in connection with the pKa values of carboxylic group.
