Unformatted text preview: Calculate the K b for aniline. 4. What is the pH of an aqueous solution prepared by adding 0.040 moles of NaOH to 1.00 liter of 0.10 M CH 3 COOH solution? Assume no change in volume. K a = 1.8 x 10-5 for CH 3 COOH 5. What mass of NaF (MW=41g/mol) should be added to 1.0 L of 1.90 M HF solution (K a = 7.2 x 10-4 ) to prepare a buffer solution of pH = 3.35? (Assume no volume change)...
