Data Analysis and Concept Development

  1. Average the blank titration values.
  2. Average the sample titration values. Subtract the average blank value from the average sample value.
  3. Using the ratio, 0.825 mg NaCl/1 mL AgNO3, calculate mg NaCl per gram of sample.
  4. Calculate the mg NaCl in the entire package of Fritos®.
  5. Calculate the mg Na in the entire package.
  6. How do your experimental values compare with the stated value on the label? Can you explain any discrepancy?

Data Table

Implications and Applications

  1. Find the recommended level of sodium intake in the daily diet.
  2. Examine a package of your favorite salty snack and find the mass of sodium listed. Calculate the mass of NaCl, and teaspoons of NaCl, assuming that one teaspoon of NaCl has a mass of approximately 6 g.
  3. If someone has a family history of high blood pressure, stroke, kidney, or heart disease, what dietary changes would a physician recommend to that person with regard to salt intake?
