Identification of Chemical Reactions

Description

Students first mix seven known solutions into any of twenty-one possible combinations, using standard lab procedures. They then observe and make notations as to how the chemicals react.

Some of the chemical reactions produced by the combinations are:
• Formation of a precipitate
• Color change
• Gas generation
• Exothermic reaction

After recording their observations, students must decide whether a chemical reaction has taken place, and provide evidence to support their deductions. As an extension, students can write the probable chemical equation of each reaction.
