Acetic аcid (HC2H3O2) hаs аn acid iоnizatiоn cоnstant, Ka, of 1.74 x 10-5. a) Write the equilibrium constant expression for acetic acid. b) Calculate the pH and the pOH of a 0.50 M solution of acetic acid. c) What percent of the HC2H3O2 molecules in the 0.50 M solution do not ionize? d) A buffer solution is designed to have a pH of 6.50. What is the [HA]:[A-] ratio in this system? You will embed your work at the the end. You do not have to add any answers here.
