Quantitative Analysis Sample Final This is an example of what the standardized final will be like. The actual exam will be 50 multiple choice questions (although because we will not be able to cover all of the material this semester, some of the questions will not be graded.) 1) X moles of NaC 2 H 3 O 2 and Y moles of HC 2 H 3 O 2 are dissolved per liter of solution. The mass balance for acetate is given by a) [C 2 H 3 O 2 - ] = X b) [C 2 H 3 O 2 - ] = X+Y c) [C 2 H 3 O 2 - ] + [HC 2 H 3 O 2 ] = X + Y d) [C 2 H 3 O 2 - ] + [HC 2 H 3 O 2 ] + [Na + ] = X + Y 2) The K a of p-nitrophenol is 7.08x10 -8 at 25º C. A 1.00x10 -3 M solution is titrated with 1.00x10 -3 sodium hydroxide. The pH at the equivalence point will be a) 8.92 b) 8.62 c) 7.15 d) 5.10 3) An excess of KI is added to 100.0 mL of an acid solution of XeO 3 . Twenty-two (22.0) mL of 0.0100 M Na 2 S 2 O 3 are required to titrate the liberated I 2 . If XeO 3 is reduced by I - to give elemental Xe and H 2 O, the molarity of the original XeO
