Post a titration curve for the polypeptide ALRHEN
Question 1 and 3 thanks EXP #9: POST-LAB 1. Draw the shape ofa titration curve of diprotic base as a strong acid is added to it. 2. If you were to plot the electrical conductivity of HCl as NAOH is added, what would a plot of electrical conductivity vs. volume NaOH look like? (Hint: Write the net ionic equation): 3. Research and explain the difference between the equivalence point of a titration and its endpoint.
A post-translational modification is a change to a polypeptide that occurs after translation. These modifications may include cleavage by a protease, such as: Question options: myoglobin restriction endonuclease ligase chymotrypsin
8. Prepare a titration curve for the titration of KHP with NaOH using the EXCEL spreadsheet template. Assume concentrations of 0.1 M for KHP and NaOH in preparing the titration curve. Attach a copy of the titration curve and explain why phenolphthalein can be used as the indicator for the titration. (3 pts) NOTE: see phthalic acid for the K, value for KHP.
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...
4. (a) Sketch an approximate titration curve for the titration of an NaOH solution with standard HCl solution. Briefly explain the shape of the curve before the equivalence point, at the equivalence point, and after the equivalence point. Chapter 4: Monitoring Acid-Base Titrations with a pH Meter (b) What would the pH be at the equivalence point of the titration in (a)? Briefly explain.
Sketch what a titration curve would look like? 1. Consider the titration of 50.00 mL of 0.01550 M NH3 with 0.03720 M HNO3. A. Sketch what a titration curve would look like for this titration, making sure to: Label both axes Illustrate a curve with the appropriate shape Indicate the location of the equivalence point on the curve (you do not need to identify its exact location on the axes) alenrennint in this titration, the titrated solution will have a...
