Preparation

• Acetone is available in finger nail polish remover.
• Prepare 3.0 M sulfuric acid by pouring 16.6 mL of concentrated acid into 63.4 mL of water.
• Prepare 3.0 M sodium hydroxide by dissolving 12.0 grams of NaOH into enough water to make 100 mL of solution.
• Prepare 2.5 M nitric acid by pouring 12.5 mL of acid into 87.5 mL of water.
• Prepare 3.0 M sodium chloride by dissolving 17.6 grams of NaCl in enough water to make 100 mL of solution.
• Prepare a 0.868 g/mL density solution by mixing 80.0 mL of ethanol with enough water to make 100 mL of solution.
• Prepare a 0.914 g/mL density solution by mixing 60.0 mL of ethanol with enough water to make 100 mL of solution.
• Prepare a 0.945 g/mL density solution by mixing 43.0 mL of ethanol with enough solution by mixing 43.0 mL of ethanol with enough water to make 100 mL of solution.
• Distilled water should have a density close to 1.00 g/mL.
• Prepare a 1.09 g/mL density solution by dissolving 12.0 grams of sodium chloride in 88.0 mL of distilled water.
• Prepare a 1.25 g/mL density solution by dissolving 54.0 grams of sucrose in 46 mL of distilled water.
• Prepare a 1.48 g/mL density solution by dissolving 45 grams of potassium carbonate in 55 grams of distilled water.
• Prepare a biodegradable container by cutting the base of a 2.0 L soda bottle. Invert the top into the base and fill the bottle with moisten soil. The soil can be enriched with lime, worms, or other materials that would simulate what is found at a dump site.
