You would like to make 100.00 mL of a 4.76 pH aceticacid/acetate buffer, in which the acid concentration is 0.070M.Write the reaction of the buffer with HCl solution. How many mL of0.100 M HCl can react with the buffer before it is exhausted? AndWrite the reaction of the buffer with NaOH solution. How many mL of0.100 M NaOH can react with the buffer before it is exhausted?

Reaction of buffer with HCl solution The pH of a buffer solution is governed by the following equilibrium CH3COOH CH3COO H The buffer solution has a large excess of CH3COOions produced by complete ionization of sodium acetate CH3COONa CH3COO Na Addition of HCl Upon addition of HCl the increase of H is counteracted by association with excess of acetate ions to form unionized CH3COOH Thus the addition of H ions are neutralized and the pH of a buffer solution remains
