Question

(a) Aqueous Be2+ ion is acidic. Write a chemical equation to account for the acidity of Be2+ ion. (b) Comment on the pKa of the following cations: Metal Ion: Na+, Be2+, Mg2+, Ca2+, Sr2+, Ba2+, La3+, Th4+ pKa: 14.1, 5.6, 11.4, 12.7, 13.2, 13.4, 8.5, 3.2 (Hint: You can separate the ions into two groups, the first group composed of ions of similar ionic radii; the second group composed of ions of same charge)
