You dissolve 25.19 mg of arsenious acid (H3ArO3 , F.W. = 125.94) in 1.00 L of water. Arsenious acid is weak, with Ka = 5.1 × 10−10. Calculate the equilibrium concentrations of H3AsO3 and H2AsO – 3 and the pH of the solution. Assume that the activity coefficients are all 1, but you must include the autoprotolysis of water.

You weight out exactly 1.00 mg of benzoic acid and dissolve it in a mixture of 2.0 mL of diethyl ether and 2.0 mL of water. After mixing and allowing the layers to separate, the ether layer is removed, dried, and concentrated to yield 0.68 mg of benzoic acid. What is the Kp value (ether/water) for this system?
