In the reaction “escaping oxygen”, what was the purpose of the potato? What is a material called that causes this behavior during a chemical reaction?
What is the purpose of crushing the Alka Seltzer tablet? What does crushing the tablet change? Why does crushing a tablet change the reaction rate?
Why does hot water change the rate at which contents mix and/or chemically react?
How did the dissolving of the sugar cube compare to the Kool-Aid? Why did this happen?
Look at your weak or strong data table. Is there an amount of vinegar at which the reaction final mass plateaus? What do you think this indicates?
In the weak or strong reaction, did a higher concentration of vinegar result in a faster rate of reaction? Explain why this may happen?
