Question

1) Calculate the pOH in an aqueous solution with a pH of 3.28 at 25°C. 2) Calculate the pH of a hydroiodic acid solution that contains 4.3×10^-3 M H3O^+ at 25°C. 3) Calculate the pH of a hypochlorous acid solution that contains 1.9 × 10^-5 M H3O^+ at 25°C. 4) What is the hydronium ion concentration of a 0.175 M acetic acid solution with Ka=1.8 × 10^-5? The equation for the dissociation of acetic acid is: 5) The acid-dissociation constant at 25.0°C for chlorous acid (HCIO2) is 1.1 × 10^-2. What is the molarity of H3O^+ ion in a 0.186 M solution of HCIO2 at equilibrium?
