What is the pH of a 0.200 M solution for HBrO? Determine the pH of each of the following solutions (Ka and Kb values are 3.0 * 10^-8 and 1.1 * 10^-8 Part A 9.00 * 10-2 M hypochlorous acid. (Ka = 2.5 x 10-9), What is the pH of a 0.185 M aqueous solution of potassium hypochlorite, KCIO? Perbromic acid | HBrO4 or BrHO4 | CID 192513 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities . b) What is the Ka of an acid whose pKa = 13. What is the pH of an aqueous solution of 0.042 M NaCN? Calculate the H+ in an aqueous solution with pH = 11.85.
