Question
identify the major speciesin solution
Identify the major species in solution (concentrations are given for the total mixture, before any reaction) for each case stated below. Once all species have been listed, pick the one(s) that will control the pH of the solution and write out the relevant equilibrium expression(s) and/or reaction(s) and state whether the solution will be acidic or basic. 0.4 M HBr + 0.3 M LiOH 0.03 M methylamine + 0.05 M ammonia 0.25 M KC2H3O2 0.65 M hydrofluoric acid + 0.65 M hypochlorous acid 0.078 M benzoic acid + 0.05 M sodium benzoate 0.55 M pyridinium chloride 0.3 M NH4NO3 +0.05 M KOH Calculate the pH of each of the solutions in #2
