This question concerns part 1 of this lab. You need to make a buffer solution by mixing both a weak acid and its conjugate base in the right proportions to achieve the desired pH. Your desired target pH is 4.20. You have been provided with 5.00 mL of 0.100 M sodium acetate solution. How many moles of acetic acid do you need to add to this solution to obtain a buffer solution at the desired pH? The pKa of acetic acid is 4.74.

7 of 21 I Review | Constants | Periodic Table Part A You need to produce a buffer solution that has a pH of 5.21. You already have a solution that contains 10. mmol (millimoles) of acetic acid. How many millimoles of acetate (the conjugate base of acetic acid) will you need to add to this solution? The pKa of acetic acid is 4.74. Express your answer numerically in millimoles. • View Available Hint(s) ΑΣφ mmol acetate
For this one, need the acid/ base tables in the book (Appendix E & F). Match each buffer system with the correct pH range the buffer maintains. Prompts Submitted Answers hypochlorous acid + sodium hypochlorite Choose a match formic acid + potassium formate 6.46-8.76 propionic acid + sodium propionate 2.77-4.77 4.76-6.76 3.89-5.89
Compare the results of two experiments: First, a small amount of base is added to an unbuffered solution with a pH of 7. Second, the same amount of base is added to a buffered solution with a pH of 7.
In Experiment 4, we used titration to determine the total acid content of samples, which we reported in terms of molarity. Reporting acidity through pH measurements is quite different, in that we can only measure the amount of the acid in its ionized form. You were tasked to investigate a clear aqueous solution of an unknown monoprotic acid. You decided to use two Chem 16.1 methods to gather data.Method 1 – TITRATION: A 10. mL aliquot of the sample was diluted with 25 mL distilled water. Two drops of phenolphthalein were added and then it was titrated 3.54 mL of 0.048 M standardized NaOH to the endpoint.Method 2 – pH STRIP: You took 1 mL of the sample and used a pH strip to estimate the pH, which turned out to be around 3.3. Another 1 mL of the sample was diluted with 9 mL of water. The pH was taken again and is now around 3.8 a) Calculate the molarity of the acid using the titration data.b) If we assume that the titrated unknown is a strong acid, predict the pH of the sample.c) Using…

Using the table of the weak base below, you have chosen Pyridine as your weak base in the buffer solution. You have already added enough of the conjugate acid salt to make the buffer solution concentration at 0.62 M in this salt. The desired pH of the buffer should be equal to 4.5.
