WitrynaA buffer solution is made by mixing 52.1 mL of 0.122 M acetic acid with 46.1 mL of 0.182 M sodium acetate. Calculate the pH of this solution at 25C after the addition of 5.82 mL of 0.125 M NaOH. A good buffer generally contains relatively equal concentrations of weak acid and conjugate base.

WitrynaHF is a weak acid due to strong Coulombic attractions since the small radii of H+ and F- ions augment the difference in electronegativity and prevent the dissociation of protons (although its weak acidic nature is also due to the presence of hydrogen bonding).
