Materials * Alka-Seltzer tablets * Empty and clean water or soda bottles (12 oz to 24 oz) * Balloons (to capture the carbon dioxide gas produced) * Water * Clock * Additional materials may be required, depending on your lab design. Procedure * Add water to a water bottle * Place Alka-Seltzer in the bottle (1) * Cover the top of the bottle with a deflated balloon making sure it’s on firmly (you can hold it down to the bottle if necessary) * Record what you see with the bottle and the balloon * Place Alka-Seltzer in a soda can * Add water * Cover the top of the bottle with a deflated balloon making sure it’s on firmly (you can hold it down to the bottle if necessary) * Record what you see with the bottle and the balloon Answer the following questions in complete sentences. 1. What two factors did you investigate in your procedure, and why did you choose to compare these two factors? The two factors I choose to investigate was the reaction time of the balloon inflating and deflating and how long it would take for it to either blow out of proportion or stay responsive. I found that they are all correlated to what I’m doing. What other factors did you need to control during your investigation? Explain how you controlled each one in your procedure. 2. What was your prediction about the results of each factor tested in your two lab procedures? Explain your predictions based on your knowledge of the dissolving process, collision theory, and reaction rates. I was thinking the balloon would inflate at a minimal pace but didn’t think the bottle would crush as result of it. Keeping the amount of water and time was imperative and double checking to make sure everything is right was prudent 3. In your own words, explain the collision theory, and what is necessary for a collision to be successful.
