1. Calculate the H3O+ and OH- concentrations according to the given pH values. Solution pH [H3O+] [OH-] Unboiled distilled water 9.02 Boiled distilled water 6.54 0.1 M NaCl solution 6.02 0.1 M NaHSO4 solution 0.73 0.1 M Na2CO3 solution 11.48 2. Calculate the Ka and Kb values for 1.0 M NaHSO4 and Na2CO3. NaHSO4 + H₂O NaSO4 + H₂O* Na₂CO3 + H₂O Na₂CHO3 + OH Hydrolysis Expression for K, and Value of K, and Ka Reaction Ka Solute NaHSO4 pH=1.02 Na2CO3 pH= 12.17
3. Calculate the pH, [H3O+],[OH-], Ka and a values. 1.0 M 0.02 PH [H3O+] HCI [OH-] pH 2.30 HC₂H30₂ [H3O+] [OH-] PH 11.8 NH3(aq) [H3O+] [OH-] HC1 + HO HC,H,O, + HO NH3 H₂O + H₂O + CI OH HCI HC,H,Oz NH3(ag) H₂O + C₂H₂O₂ + NHÀ Ka a Ka a Ka a [C₂H₂O₂] = [H₂O] [NH] = [OH] 1.0 M
