Al(H 2 O) 6 3+ (aq) + H 2 O (l) H 3 O + (aq) + Al(H 2 O) 5 (OH) 2+ b. H 2 O (l) + HONH 3 + (aq) HONH 2 (aq) + H 3 O + (aq) c. HOCl (aq) + C 6 H 5 NH 2 (aq) OCl - (aq) + C 6 H 5 NH 3 + (aq) 44. Fill in the missing information in the following table. pH pOH [H + ] [OH - ] Acidic, Basic, or Neutral? solution A 9.63 solution B 3.9 x 10 -6 M solution C 0.027 M solution D 12.2 50. A solution is prepared by mixing 90.0 mL of 5.00 M HCl and 30.0 mL of 8.00 M HNO 3 . Water is then added until the final volume is 1.00 L. Calculate [H + ], [OH - ], and the pH for this solution.
