4) Draw the titration curves for the amino acids Lysine and Alanine. Be sure to label your axes. (5 pts) a) Identify the pKi, pK and pKR (if relevant) for each amino acid. b) Identify the buffering region around pKR for arginine c) Identify the pl of each amino acid d) Draw the structure of the primary chemical species in each pH region of the titration curve.
Locate the isoelectric point on the titration curve and drag the pl label to that point. Fill in the labels on the x axis of this titration curve.
Draw the titration curve of sodium maleate by strong acid. Label the following points of the titration curve: initial, pKA1, 1st equivalence point, pKA2, 2nd equivalence point. Be careful assigning the pKA’s!
Draw and label the titration curve of 1M histidine starting at pH 1.0 with 1.0M NaOH
13. Sketch a titration curve for the titration of a monoprotic weak acid HA with a strong base. The titration reaction (neutralization) is: HA + OH + H2O+ A On the curve, clearly label the points that correspond to: i. the equivalence point ii. the region with maximum buffering iii. pH = pka iv. pH depends only on [HA] v. pH depends only on [A-] vi. pH depends only on amount of strong base added.
This is incorrect. What are the titration points for this titration curve? The pH values, respectively at 0 mL is 9.16, at 10 mL pH is 5.56, at 20 mL pH is 4.98, at the equivalence point the pH is 3.24, at one half equivalence point the pH is 5.23, at 40 mL the pH is 1.87, at 50 mL the pH is 1.60. Use your calculations to make a sketch of the titration curve. Label Titration curve : y...
