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
