A quantity of 0.15 M hydrochloric acid is added to a solution containing 0.10 mol of sodium acetate. Some of the sodium acetate is converted to acetic acid, resulting in a final volume of 650 mL of solution. The pH of the final solution is 4.56.
a. What is the molar concentration of the acetic acid?
b. How many milliliters of hydrochloric acid were added to the original solution?
c. What was the original concentration of the sodium acetate?
