Results/Questions 1. What evidence did you see in the experiment that a chemical reaction took place?
2. When citric acid reacts with baking soda, a salt, water and a gas are produced. What is the name of the gas?
3. In two or more complete sentences, explain the law of conservation of mass and how it relates to this experiment?
4. When vinegar, an acid, is mixed with baking soda, a base, the reaction is similar to the reaction of Alka-Seltzer and
water, a salt, water and carbon dioxide are produced. In two or more complete sentences, describe how your
knowledge of balancing chemical equations can help you to determine the missing compound.
NaHCO3 + HC2H302 -
+ H2O + CO2
5. In two or more complete sentences, design an extension of this experiment to determine the mass of the carbon
dioxide gas that was produced. Include a hypothesis regarding the mass of the gas in grams.
