Unformatted text preview: 5. Calculate the molar ratio of acetate to acetic acid required to have a buffer with a pH =5.30 . 6. Calculate the pH and [H + ], and [OH − ] concentration for a solution prepared by mixing 20.0 mL of 0.25 M acetic acid and 10.0 mL of 0.25 M sodium acetate. 7. Calculate the pH of a solution prepared by adding 20.0 mL of 0.25 M acetic acid with 2.0 mL of 0.75 M potassium hydroxide solution. In consideration of the Henderson-Hasselbach equation, what would you expect to be the effect on the pH of the buffer if 50.0 mL of carbonate-free water was added to dilute the buffer?...
