WebQuestion: 8. Draw the titration curve for arginine. Label the midpoint(s) and equivalence point(s). Draw the structure of arginine at each important part of the titration curve. amino acid alanine arginine asparagine aspartic acid cysteine glutamic acid glutamine glycine histidine isoleucine leucine lysine methionine phenylalanine proline serine threonine … WebTitration of valine by a strong base, for example NaOH, reveals two pK's. The titration reaction occurring at pK2 (pK2 = 9.62) is: NH2—CH3+—COO−. In a highly basic solution, pH = 13, the dominant form of glycine is: a net positive charge.
