Types of Chemical Reactions
▶︎ Watch it animatedinteractive step-through · ~3 min · optionalMost reactions fall into a few types, sorted by what is transferred. Acid-base reactions transfer a proton (H⁺); precipitation reactions combine ions into an insoluble solid; oxidation-reduction (redox) reactions transfer electrons. Classifying a reaction tells you which tools to apply.
The skill is reading the reaction for its signature: a proton moving (acid-base), an insoluble product forming (precipitation), or oxidation states changing as electrons move (redox). Recognizing the type is the entry point to analyzing it.

Lesson
Types of Reactions
›
Acid-base, precipitation, and redox reactions are told apart by whether a proton, a solid, or electrons transfer. The lesson classifies reactions by signature, then closes with a ten-scenario check.
Diagnostic
10-item topic check
›
Ten items on classifying reactions: identifying acid-base (proton transfer), precipitation (insoluble solid), and redox (electron transfer) from the reaction.

Pick one of the failure modes you missed and drill it on its own. The round is adaptive: two correct in a row clears the misconception and moves you to the next.
