CHEMISTRY HOUSEHOLD PRODUCT SURVEY

Directions: Tonight, enlist the support of your parents and siblings to complete the following survey of home products. If you work together the survey can be completed very quickly. You will have fun and you will teach your family a little chemistry! Together, go to the following locations: choose 2 products from each location and make a complete ingredients list of each product. After completing this walk-thru survey, compare and contrast the different ingredients. Explain any similarities between ingredients. For example did you find similar ingredients in more than one product? Ask your parents this question: Why is label reading such a necessity in today’s world?

Conservation of MassIn a chemical reaction, the total mass of the substances formed by the reaction is equal to the total mass of the substances that reacted. This principle is called the law of conservation of mass, which states that matter is not created or destroyed during a chemical reaction. In this experiment, sodium hydrogen carbonate, NaHCO3 (baking soda), will react with hydrochloric acid, HCl. The substances formed by this reaction are sodium chloride, NaCl; water, H2O; and carbon dioxide gas, CO2.

StrategyYou will show that new substances are formed in a chemical reaction. You will show the conservation of mass during a chemical reaction.

Materials sealable plastic sandwich bag containing sodium hydrogen carbonate, NaHCO3 hydrochloric acid, HCl plastic pipette paper towel metric balance

ProcedureObtain the plastic sandwich bag containing a small amount of sodium hydrogen carbonate.

Fill the pipette with the hydrochloric acid solution. Use a paper towel to wipe away any acid that might be on the outside of the pipette. Discard the paper towel. WARNING: Hydrochloric acid is corrosive. Handle with care. Carefully place the pipette in the bag. Press the bag gently to eliminate as much air as possible. Be careful not to press the bulb of the pipette. Seal the bag.

Measure the mass of the sealed plastic bag using the metric balance. Record this value in the Data and Observations section.

Remove the plastic bag from the balance. Without opening the bag, direct the stem of the pipette into the sodium hydrogen carbonate. Press the bulb of the pipette and allow the hydrochloric acid to react with the sodium hydrogen carbonate. Make sure that all the acid mixes with the sodium hydrogen carbonate.

Observe the contents of the bag for several minutes. Record your observations in the Data and Observations section.

After several minutes, measure the mass of the sealed plastic bag and its contents.

Record this value in the Data and

Data and ObservationsTable 1Mass of plastic bag before reaction (in grams)

32

Observations from step 6 Mass of plastic bag after reaction (in grams)

Questions and ConclusionsWhy was it important for the plastic bag to be sealed?

What did you observe that indicated that a chemical reaction took place?

Compare the mass of the plastic bag and its contents before and after the chemical reaction.

Does your comparison in question 3 confirm the conservation of mass during this chemical reaction? Explain.

Strategy Check_____ Can you demonstrate that new substances are formed in a chemical reaction? _____ Can you show the conservation of mass during a chemical reaction?
