Determine the pH of each of the following solutions. (a) 0.382 M hypochlorous acid (weak acid with Ka = 3e-08). (b) 0.900 M hypoiodous acid (weak acid with Ka = 2.3e-11). (c) 0.597 M pyridine (weak base with Kb = 1.7e-09).
suggest another small molecule that like water and ammonia might make a good ligand. remember that ligands are electron pair donors which means that one atom must have a lone pair of electrons on it. draw lewis dot structure of the molecule you th..
