Enter your answer in the provided box. How much HCl must be added to a liter of buffer that is 1.6 M in acetic acid and 0.70 M in sodium acetate to result in a buffer pH of 4.20?
A buffer solution is prepared by dissolving 1.000 g of sodium acetate (CH2COONa) into 100.00 mL of a 0.100 M solution of acetic acid. Then 1.80 mL of a 10.00 M solution of hydrochloric acid is added to the acetic acid/sodium acetate buffer solution. The K, of acetic acid is 1.8 x 10-5. What is the pH of the solution after adding HCI? pH
Q. A buffer solution prepared by mixing 50.00 mL of 0.200 M acetic acid and 50.00 mL of 0.200 M sodium acetate (Ka, acetic acid = 1.76 x 10-5). (Hint: Calculate the pH using the Henderson-Hasselbach equation, remember to allow for the dilution effect when mixing the two solutions together.)
