Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

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.

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.
Twenty tablets (labelled 300 mg aspirin per tablet) had a total mass of 6.9117 g. The tablets were powdered and 0.5423 g of powder was added to 30.0 mL 0.494 M sodium hydroxide solution and the mixture boiled gently for 10 minutes. The excess alkali in the cooled solution was titrated with 0.475 M hydrochloric acid solution and 20.25 mL required for neutralization. Given that aspirin (C9H8O4) and NaOH react in a 1:2 ratio calculate the percentage of aspirin as compared to the labelled claim. Aspirin Mr(C9H8O4) = 180.2
