A student prepares an acetic acid/sodium acetate buffer by mixing 10.00 mL of 0.50 M acetic acid with 0.4102 g of sodium acetate, and diluting to 100.00 mL. This buffer is then tested by adding 0.10 M HCI and 0.10 M NaOH, and the following data is obtained: 0.10 M HCI added 0.10 M NaOH added Buffer Volume (mL) 40.00 40.00 Amount of Acid/Base Added (ml) 17.06 18.71 Initial pH 4.75 4.75 Final pH 3.72 5.78 1: Calculate the concentration of acetic acid and acetate ion in the buffer. Considering these concentrations, what is significant about the initial pH of 4.75? 2: Which component (Acetic acid or Acetate ion) reacts with HCI? Which component (Acetic acid or Acetate ion) reacts with NaOH? Write the balanced neutralization reaction for both.
