In this lesson, students use a temperature probe to investigate an acid-base reaction in order to write balanced chemical equations and determine mole ratios.

In this inquiry experiment, students will

• Identify variables, design and perform the experiment, collect data, analyze data, draw a conclusion, and formulate a knowledge claim based on evidence from the experiment.
• Measure the temperature changes of a series of reactions.
• Determine the stoichiometry of a reaction in which the reactants are known but the products are unknown.
