1a. Write out the reaction for acetic acid (CH3COOH) and water. 1b. Calculate the pH of a 0.15 M solution of acetic acid, which has a K₂ of 1.8 x 10-5 1c. What would happen to the pH of the solution if you added some sodium acetate (NaCH3COO) to it? Why? (Hint: NaCH3COO contains the conjugate base of CH3COOH) Describe how the acetate ion would interact with the reaction of acetic acid in water that you wrote in part A. 1d. If it was 0.10 M sodium acetate that was added in part C, what would be the new pH value?
