Infоrmаtiоn fоr Question 1 (5 points) The titrаtion curve for Histidine is shown here. Question 1 refers to this titrаtion curve. Answer the following questions with the letter on the curve that signifies the correct position on the curve. (1 pt. each) Image Description The graph titled “Histidine Titration” illustrates the titration curve of histidine, depicting the relationship between pH and the equivalents of OH⁻ (hydroxide ions) added. The x-axis represents the equivalents of OH⁻ added, ranging from 0 to 3.0, and the y-axis represents the pH, ranging from 0 to 12. Key points labeled A, B, C, D, E, and F mark significant stages in the titration process. Point A is at approximately pH 2. Point B, around 0.5 equivalents OH⁻ and pH 3. Point C, at around 1.0 equivalents OH⁻ and pH 6. Point D, around 1.5 equivalents OH⁻ and pH 8. Point E, at around 2.0 equivalents OH⁻ and pH 9. Finally, Point F, at around 3.0 equivalents OH⁻ and pH 11.
