Question Description
Set up the experiment
Get four 8 oz. cups from the lab kit. Place a piece of tape on each cup or glass. Using a pen or marker, label the tape on each cup with one of the following percentages: 0%, 1.75%, 3.5%, and 7%.
Using the graduated cylinder, measure out 100 mL of distilled water. Pour the water into the fifth, unlabeled cup.
Measure out 1.5 level teaspoons of salt and add it to the unlabeled cup containing 100 mL of distilled water. Mix completely. This is the 7% salt solution.
Using the graduated cylinder, measure out 50 mL of this mixture and pour it from the graduated cylinder into the cup labeled 7%.
Add distilled water up to the 100 mL mark of the graduated cylinder to make the next dilution. Adding 50 mL distilled water to 50 mL of a 7% solution will result in 100 mL of a 3.5% solution.
Using the graduated cylinder, measure out 50 mL of the 3.5% solution and pour it from the graduated cylinder into the cup labeled 3.5%.
Add distilled water up to the 100 mL mark of the solution in the graduated cylinder to make the next dilution. Adding 50 mL of distilled water to the 50 mL of the 3.5% solution will result in 100 mL of a 1.75% solution.
Using the graduated cylinder, measure out 50 mL of the 1.75% solution and pour it from the graduated cylinder into the cup labeled 1.75%.
Empty the remaining 1.75% solution down the drain of the sink and rinse out the graduated cylinder with tap water.
