trigger Posted January 6, 2009 Report Posted January 6, 2009 At 25 °C, the equilibrium constant Ka, for hydrofluoric acid is7.2 × 10^−4 mol dm^−3 and the equilibrium concentration of HF(aq) is0.01 mol dm^−3. Calculate the equilibrium concentrations of H^+(aq) and F^−(aq) and hence the pH of the acid solution. (Can your answer for pH be given to 2 significant figures.) Quote
