SUMMARY
The discussion focuses on the titration of an unknown amino acid solution using standard 0.1521M NaOH and 0.0986M HCl to determine the concentration of the amino acid. The student performed titrations with 18.61mL of NaOH and 3.28mL of HCl, applying the equation M1V1=M2V2. It was concluded that the amino acid exists in both its protonated (A) and deprotonated (A-) forms, which must be considered when calculating the concentration.
