Question- The ionization constant for hypochlorous acid (HClO) IS Ka= 2.8 x 10^-8 at T= 25 C. Find the pH for the following two solutions: Solution 1- An aqueous solution that is 0.0500 M in HClO. Solution 2- An aqueous solution that is 0.0500 M in HClO and 0.0200 M in NaClO, the sodium salt of the conjugate base of hypochlorous acid.
