Last unit we explored how the amount of reactant will affect the amount of product produced. We want to expand upon this knowledge and explore how the amount of reactant affects other factors in chemical reaction. Read through the protocol below and determine which ionic compound you will use and the amounts of that compound you will use for each trial before starting your investigation.

Protocol Investigation 2.A – Vary the amount of ionic compound

• You will need to choose one ionic compound to test, from the ionic compounds tested in Investigation Part 1.
• You will need to vary the amount of ionic compound, staying within the 1-3 gram range.
• You will need to keep the amount of water constant, at 5 mL.
• You will need to record the initial temperature of each individually as well as the greatest difference in temperature from the starting temperature of the water/ionic compound mixture.
• Complete three trials.
