Buffer's 1c
WebThe conjugate base of a strong acid would be an exceedingly weak base and so it would be severely limited in neutralizing additional acid. Essentially the addition of more acid would lower the pH even more so. The purpose of a buffer is to resist these drastic changes in pH so a strong acid buffer wouldn't really be achieving that. WebExample: Calculate the pH of the buffer prepared earlier (100.0 mL of 0.10 M phosphate buffer at pH 7.40) after the addition of 1.00 mL of 1.0 M HCl. NOTE: The HCl will react with the conjugate base in the buffer (HPO 4 2−). Therefore the new concentrations of the weak acid and conjugate base in the buffer must be calculated.
