1. i) (15 points) Sketch the titration curve of the following hypothetical amino acid, if you titrate it with 0.1M HCl. Assume your amino acid is at physiological pH at the beginning of the titration. Label everything on your titration curve clearly for full credit. pKa ( a NH3") = 9.2, pka ( a COOH) = 2.5, pka (RCOOH) = 4.5
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.
Titrations Part A Identify each type of titration curve. Note that the analyte is stated first, followed by the titrant.Drag each graph to the appropriate bin. Strong acid-strong base Weak acid-strong base Weak base-strong acid Polyprotic acid-strong base
Sketch a pH vs. Volume added graph (titration curve) for a diprotic acid being titrated with NaOH. Label the axis and equivalence points.
Identify the half-equivalence point of the weak base- strong acid titration curve in the above graph.
Use the titration curve of a weak acid with a strong base below to answer the following questions. Identify the Equivalence Point of Titration and label it on the titration curve below. (ii) What is the Titrant (iii) From the graph, what is the [H^+] and the volume of NaOH used to reach the equivalence point. (iv) Calculate the [OH^-] at the equivalence point (v) What is the pKa of the acid used for titration? (vi) Calculate the Ka of...
Part The following data was collected from the titration curve. Identify the values for pka, pka , and paz. Volume (mL) 1.95 2.45 10.08 5.27 20.15 30.23 7.42 40.3 50.38 8.39 9.75 10.54 60.45
To learn about titration types and how to calculate pH at different points of titration. In an acid-base titration, a titrant (solution of a base or acid) is added slowly to an analyte (solution of an acid or base). The titration is often monitored using a pH meter. A plot of pH as a function of the volume of titrant added is called a pH titration curve. Prior to the titration, the pH is determined by the concentration of the...
Sketch a titration curve of pH vs. volume of base added for both acids, and plot the pKa’s. The two acids are Acetic acid (CH3COOH) (pKa = 4.74) and Phosphoric acid (H3PO4) (pKa = 2.14).
How do you find all of the other points to plot for a titration curve graph when only given the pka? Example: Draw the titration curve for propionic acid, whose pka=4.87
