404 Stoich Lab Part 1:   Sodium Chloride and Silver Nitrate reaction
  • Write all answers in your bound journal
  • Make it NEAT and in COMPLETE SENTENCES, clearly identify which section you are working (using numbers)
  • Box final answers if doing math.
  • -4pt if you do not title and date the entry
  • -1pt (per infraction) if you do not clearly identify the sections, or number the problems

 
    LAB PROTOCOL (20 pts)
     
  1. For the following reaction (sodium chloride reacts with silver nitrate.), show the:
    1. Molecular equation
    2. Name the type of reaction
    3. Predict the solubility of the reactants and the products
    4. Write the complete ionic equation
    5. Write the net ionic equation
  2. Weigh out ~ 0.500 grams of sodium chloride. Please record actual mass of the sodium chloride in your notebook (use a complete sentence)
  3. HYPOTHESIZE: How many mLs of 0.500M silver nitrate will be needed to react with the above mass of sodium chloride?
  4. What are the theoretical masses of the products?
  5. Show and explain the experiment to Dr. Duick before starting!
  6. Add the Sodium chloride to 50.ml of water in a beaker and mix until dissolved. What is the molarity of the solution?
  7. Add the hypothesized silver nitrate solution and note the reaction.
  8. What compound are you seeing?
  9. Measure the weight of the filter paper and write it (in pencil) on the edge filter paper.
  10. Decant the solution onto the filter paper, be careful in trying to contain all of the percipitant.
  11. Let the filter dry overnight in the fume hood, it will be weighed the next class meeting time.
    NEXT MEETING TIME
  12. Weigh the filter paper and product.
  13. Subtract the mass of the filter paper (written on the edge) to get just the mass of the product.
  14. What is your percent yield of the product? (Percent Yield = (Actual Yield/Theoretical Yield) x 100%)
  15. What is your percent error for product recovery? (Percent Error = ((Theoretical Yield - Actual Yield)/ Theoretical Yield) x 100%)
  16. If percent yield or percent error resulted in unexpected values, what might have contributed to these results?
