Reaction Types Lab
Not a proper inquiry lab. This multi-day lab involves five common reactions:
- Burning Mg wire
- Calcium carbonate precipitation
- Iron / Copper(II) replacement
- Neutralization
- Zinc & Acid
It asks students to use observations to confirm the products they've predicted, and to label phases in the reaction.

Will a single replacement reaction actually happen?
As an enrichment in Chem 11, I teach the activity series. In this experiment (also used for redox analysis in Chem 12), students can observe which combinations of metals & ions actually result in a chemical change.

Will a double replacement reaction actually happen?
As an enrichment to solution chemistry, I used to teach basic solubility rules and have students build a solubility chart from experiment. I've since realized that this fits nicely with reaction types, since some hypothetical double replacements don't actually result in any chemical change. Students combine ionic solutions and look for the formation of solids. They identify the solids by process of elimination.
