Question

The fizzing that is seen when an Alka-Seltzer tablet is dropped in acid is the same sort of fizzing reaction that can be seen when baking soda is mixed with vinegar. The chemical equation is shown below. You will be watching the lab from this video OR completing the lab for 5 points extra credit.

The third product being formed that fills up the balloon in this experiment is carbon dioxide as a gas (option b).

Answer 3

[AI-generated answer — Explain Bot]

Based on the information given, the fizzing reaction observed when an Alka-Seltzer tablet is dropped in acid is similar to the reaction when baking soda is mixed with vinegar. In both cases, a chemical reaction occurs that results in the formation of gas.

The chemical equation for the reaction between baking soda and vinegar is:

NaHCO3 (s) + CH3COOH (aq) -> CO2 (g) + H2O (l) + CH3COONa (aq)

From this equation, it is clear that one of the products formed is carbon dioxide gas (CO2). This is the gas that fills up the balloon in the experiment. Therefore, the correct answer to the question is b) Carbon dioxide as a gas.
