27. Calculate the pH of the following aqueous solution: 0.66 M NaF (pKa for HF = 3.14) (A) 5.52 (B) 2.96 (C) 8.48 (D) 11.04 (E) none of these

35. The complex ions of Zn2+ are all colorless. The most likely explanation for this is: (A) Zn2+ is paramagnetic. (B) Zn2+ exhibits “d orbital” splittings in its complexes such that they absorb all wavelengths in the visible region. (C) Since Zn2+ is a d10 ion, it does not absorb visible light even though the “d orbital” splittings are correct for absorbing visible wavelengths. (D) Zn2+ is not a transition metal ion. (E) None of these is correct.
