POST-QUESTIONS 1. After a student dissolved 0.5 g of white solid in water, she tested the conductivity and determined that the solution did not conduct electricity. The student then concluded: "when the white solid dissolved it 'just disappeared' so some sort of error must have been made because all solids are ionic compounds and, therefore, are electrolytes." Comment on the student's conclusion. Is her statement a valid conclusion? If so, identify what is correct. If not, write a conclusion that would be correct.

Post-lab Question #5: Rank the following aqueous solutions in order of increasing freezing points (lowest to highest temperature): pure H2O, 0.10 m BaCl2, 0.10 m glucose, 0.20 m Na2SO4, and 0.20 m NaCl. Na2SO4, NaCl, BaCl2, glucose, pure H20 pure H20, Na2SO4, NaCl, BaCl2, glucose NaCI, Na2SO4, BaCl2, glucose, pure H20 pure H20, glucose, BaCl2, NaCl, Na2SO4

The following evidence was obtained from an experiment to determine the molar concentration of a sodium nitrate solution. A sample of sodium nitrate solution was evaporated to dryness and the mass of solid residue was measured.Evidence:Volume of solution = 10.00 mLMass of beaker = 79.54 gMass of beaker and residue = 82.96 gFrom this data, calculate the molar concentration of the original sodium nitrate solution. Record only your numerical answer with the correct number of significant digits.  You do not need to include units as the units appear for you beside the answer box already.
