1. Ironfilings
...Distilled water bottles BACKGROUND In this lab, a solution of copper(II) sulfate will be added to iron filings. The reactants are given below. What type of reaction is this? What will the products be? Fe + CuSO Notice from the balanced equation of the reaction the relationship between the number of moles of iron that react and the number of moles of copper that are produced. What is the molar ratio between iron and copper for this reaction? PROCEDURE 1. On a piece of weighing paper mass out about 2 grams of iron filings. Record mass to the nearest .01 2. Measure out 50 mL CuSO solution in a graduate...

5. Acidity of Foods
...rankings will be the same. The titration of the vinegar provides a chance to do something quantitative with the results. Inexpensive white vinegar with 5% acidity is recommended. Since each molecule of NaOH supplies one hydroxl ion and each acetic acid molecule supplies one hydrogen, the number of moles of acid in the 10 mL sample of the vinegar equals the number of moles of NaOH used in the titration. Example Calculation: 16.9 mL of .5 M NaOH used .5 moles in 1000 mL .5 X (16.9 / 1000) = .00845 moles NaOH used 1 mole of acetic acid = 60 g. .00845 X 60 = .507 g. in the 10 mL sample of vinegar, or 5...
