CHM 24100 Spring 2011 Problem Set 5 Due March 25 Ch. 4: Ex, 4.2 (HSO 4 - , H 2 PO 4 - ), 4.13, 4.14f, 4.15, 4.27c. Pr. 4.12a A. Give an example of an acidic, a basic, and an amphoteric oxide from the same family in the Periodic Table. B. Arrange the following binary oxides in order of increasing Bronsted acidity in aqueous solution. Cite a periodic trend or property that motivates your answer. Which of the series is most likely to be amphoteric? CaO, MgO, Al 2 O 3 , SiO 2 , CO 2 C. Predict the thermodynamically favorable direction for each of the following, and account for your reasoning. (i) CH 3 OH(g) + HCl(g) = CH 3 Cl(g) + H 2 O(g) (ii) 5 PF 3 (g) + 3 PCl 5 (s) = 5 PCl 3 ( l ) + 3 PF 5 (g) D. Identify the following as Lewis acids or bases and rank them in order of increasing hardness. Explain your reasoning. O(CH 3 ) 2 S(CH 3 ) 2 Se(CH 3 ) 2 Chapter 5: Ex. 5.1, 5.6, 5.9a, 5.11c, 5.16, 5.17. Pr. 5.9c E. The figure below is part of the modified Latimer diagram for nitrogen under conditions of 1.0 M OH - (aq). Identify the species in the Latimer diagram provided that are unstable

Unformatted text preview: with respect to disproportionation in 1.0 M hydroxide. State your reasoning. Calculate x. 01 . NO 3-NO 2- 46 . NO 85 . N 2 X + 0.41 F. Chlorine reacts with aqueous bromide ion in acid solution to give a red liquid A and another product B . In base A converts to a mixture of bromide ion and a second bromine-containing species C . In base perbromate ion reacts with bromide to generate essentially one bromine-containing product C . Identify the chemical species A , B , and C . Hint: Figure 17.14 in the text may be useful. NaBr(aq) + Cl 2 (aq) A(liq) + B OH-C + Br-(aq) BrO 4-(aq)...
