Question

2. A buffer solution contains 0.120 M acetic acid and 0.150 M sodium acetate. a. How many moles of acetic acid and sodium acetate are present in 50.0 mL of solution? b. If we add 5.55 mL of 0.092 M NaOH to the solution in part (a), how many moles of acetic acid, sodium acetate, and NaOH will be present after the reaction has finished? c. If we add 0.50 mL of 0.087 M HCl to the solution in part (a), how many moles of acetic acid, sodium acetate, and HCl will be present after the reaction is complete?

Step 1

First, we need to find the moles of acetic acid and sodium acetate in the initial 50.0 mL buffer solution. Moles of acetic acid = Molarity × Volume (in L) Moles of acetic acid = 0.120 M × 0.050 L = 0.006 mol Moles of sodium acetate = Molarity × Volume (in Show more…
