Part A: Calculate the pH of a 0.316 M aqueous solution of hydrofluoric acid (HF, K_a = 7.2Ã10^-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, K_a = 1.4Ã10^-3) and the equilibrium concentrations of the weak acid and its conjugate base.

pH=? [CH₂ClCOOH]_equilibrium = ? [CH₂ClCOO^- ]_equilibrium = ?
