Plan and Conduct an Inquiry
Purpose
Your task is to plan and conduct a lab activity into how ONE of the following factors affect the rate of a chemical reaction: change in temperature (ex. hot vs. cold water), increased surface area (i.e. particle size), change in concentration or increased pressure.
Possible questions for testing:
- How does concentration of the reactants affect the reaction rate?
- How does the surface area of the reactants affect the reaction rate?
- How does temperature affect the reaction rate?
- How does pressure affect the reaction rate?
You are to design a lab report to test these factors using only the necessary materials below:
Materials
- Antacid tablets
- Ice water
- Warm water
- Vinegar
- Baking soda
- Clear drinking glasses (or beakers)
- Mortar and pestle
- Small sealable container (ex. camera film container)
- Stopwatch
- Thermometre
