WebWhat is the pH of a 0.15 M solution of acetic acid, HC2H3O2 ? Ka = 1.8 x 10^-5 This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you … WebThe concentration of carbonic acid, H 2 CO 3 is approximately 0.0012 M, and the concentration of the hydrogen carbonate ion, HCO 3 −, is around 0.024 M. Using the Henderson-Hasselbalch equation and the p Ka of carbonic acid at body temperature, we can calculate the pH of blood: pH = p K a + log [ base] [ acid] = 6.4 + log 0.024 0.0012 = 7.7

WebMar 29, 2024 · The Ka of HC2H3O2 is found by calculating the concentrations of the reactants and products when the solution ionizes and then dividing the concentrations of the products multiplied together over the concentration of the reactant. For HC2H3O2, the formula for Ka is Ka = [H3O+] [C2H3O2]/ [HC2H3O2]. WebCalculate the pH of a buffered solution prepared by dissolving 21.5 g benzoic acid (HC7H5O2) and 37.7 g sodium benzoate in 200.0 mL of solution. arrow_forward A good buffer generally contains relatively equal concentrations of weak acid and conjugate base. can guinea pigs get pink eye
