Part A: Calculate the pH of a
0.316 M aqueous solution of hydrofluoric
acid (HF, Ka =
7.2×10-4) and the equilibrium
concentrations of the weak acid and its conjugate base.
pH=? [HF]equilibrium= ? [F-]equilibrium= ?
Part B:Calculate the pH of a
0.0193 M aqueous solution of chloroacetic
acid (CH2ClCOOH, Ka
= 1.4×10-3) and the equilibrium
concentrations of the weak acid and its conjugate base.
pH=?
[CH2ClCOOH]equilibrium = ?
[CH2ClCOO-
]equilibrium = ?
