The strong acid H2SeO4 will completely ionize in water, however the conjugate base can then act as a acid an ionize further. The second Ka, Ka2 for HSeO4 is 1.2 x 10-2. This second Ka is not insignificant, being stronger than many other weak acids. A. Calculate the [H3O+] for a solution of 0.150 M H2SeO4. B. Using the value calculated above, calculate the value of [H3O+] for both ionizations of the acid. Grading will be based on the...

Aluminum ion in solution reacts with water to form aqueous hexaaguaaluminum ()ion. Write this reaction below, remember phases. Aluminum is more likely to form a hydrated complex than the other four ions remaining in solution, because of its relatively small size and high charge To separate the Group B2 ion, the solution first is made basic by adding ammonia. In the presence of this weak base the pH is adjusted to 9-10 and the group B ions form insoluble hydroxides....
