Question 4. a.) Calculate the pH of a solution initially 0.1 M in acetic acid and 0.02 M in sodium acetate. The pKa for acetic acid is 4.76. b) Calculate the pH of the buffer if you add 10 ml of 0.1M HCl to 100 ml of the buffer in part a.
a.) Given a 0.1 M solution of acetic acid and sodium acetate, describe how you would prepare 1.0 L of 0.1 M acetate buffer at a pH of 5.4 (the pKa of acetic acid is 4.75). Show all work. b.) With this new solution, what would the pH of the Buffer be when a 0.01 M solution of NaOH is added?

Please Help a) Calculate the pH of a solution initially 0.1 M in acetic acid and 0.02 M in sodium acetate. The pKa for acetic acid is 4.76. B) calculate the pH of the buffer if you add 10 ml of 0.1 M HCL to 100ml of the buffer in part a.
What should the pH of a solution of 1.0 mL of 0.1 M acetic acid and 1.0 mL of 0.1 M sodium acetate and 48.0 mL of water be? Justify your answer.
calculate the pH for a buffer solution made from a 3:1 ratio of 0.1 M acetic acid and 0.1 M sodium acetate. (pKa of acetic acid is 4.76)
12. The pH of a solution that is 0.25 molar in acetic acid and 0.1 molar in sodium acetate is 4.36. What is the pka of acetic acid? 3.96 B) 4.76 C) 5.96 D) 7.76 E) none of the above
Starting with a solution at equilibrium containing 0.5 M acetate and 0.5 M acetic acid, then adding 0.1 sodium acetate, what would the pH of the original solution and the solution after the addition be? Acetic acid Ka 1x10-6 (use this cant use calculator on test) PLEASE EXPLAIN
Acetic acid has a pKa of 4.74. A stock solution of 1.0 M acetic acid is available. A stock solution of 2.0 M potassium acetate is available. Show all the calculations and explain how to make 560.0 mL of 250. mM acetate buffer that has a pH = 5.0. (Hint: first make a 250 mM potassium acetate solution and a 250 mM acetic acid solution. Then determine how much of each to use.). pH = pKa + log {[acetate]/[acetic acid]}
What is the pH of a solution that is 0.100 M in acetic acid and 0.150 M in sodium acetate? pKa of acetic acid = 4.76 A. 6.26 B. 4.58 C. 2.94 D. 4.94
