A student made a mistake while preparing an acetic acid/acetate buffer. They intended to prepare 100. mL of pH 4.85 buffer, but combined 15.0 mL of 0.100 M CH;COOH with 85.0 mL of 0.100 M CH;COONA by mistake, resulting in a pH 5.50 solution. They used a 3.0 M HCl solution to correct the buffer's pH. What volume of a 3.0 M HCl solution must be added to correct the buffer pH to 4.85?
