What is the pH of a 0.25 M solution of NaCH3COO (Ka (CH3COOH) = 1.8 * 10-5)? Instruction: Please have two decimal places for your answer
1.) You have two buffered solutions. Buffered solution 1 consists of 5.0 M HOAc and 5.0 M NaOAc; buffered solution 2 is made of 0.050 M HOAc and 0.050 M NaOAc. How do the pHs of the buffered solutions compare? (Note: Ac– = acetate ion, CH3COO–). A. The pH of buffered solution 1 is greater than that of buffered solution 2. B. None of the answers are correct C. The pH of buffered solution 1 is equal to that of...
Acetic acid, HOAc, has a Ka = 1.73x10^-5. You need to prepare a buffer solution with a pH of 5.00 from a solution of 1M acetic acid (HOAc) and 1 M sodium acetate (NaOAc). How many mL of NaOAc should be added to the 30mL of HOAc solution to create the buffer? Using this buffer as an example, provide the reactions that allow the buffer to resist changes in pH upon addition of 1) NaOH and 2) HCl.
