29. A 0.100 m K2SO4 solution has a freezing point of -0.43°C. What is the van't Hoff factor for this solution? Kf = 1.86°C/m (A) 0.77 (B) 1.0 (C) 2.3 (D) 3.0 (E) >3.0

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.
