Part 1)A buffer solution contains 0.125 M acetic acid and 0.150 M sodium acetate. The pKa of acetic acid is 4.74. Use the Henderson-Hasselbalch equation to calculate the solution’s pH. Part 2)A buffer solution is prepared by mixing 2.00 ml of 0.500 M acetic acid and 10.00 ml of 0.500 M sodium acetate. Calculate the acetic acid concentration in the buffer solution. You will need to use dilution calculations.
Your goal is to make a buffer with a pH of 4.95 from acetic acid and sodium acetate. Assume the pKa for acetic acid is 4.74. What is the volume of acetic acid added to make your buffer? Report your answer to the tenths place. To do this, we use the Henderson-Hasselbach Equation pH = pkA + log (base/acid) where pkA = 4.74 for acetic acid, pH = target pH and [base] /[acid] = x/(1-x) since we don't know the concentration of the base, we will call it x the acid is just 1-x, assuming the two add up to 100% solve for x, and then you know the mL of base and acid to add.
