oxidation reduction

I teach Redox and Electrochemistry as the first topic in AP Chemistry¹.

Galinstan is the tradename for a liquid metal alloy that is comprised of three elements: gallium (68.5%), indium (21.5%), and tin (10%).¹ It behaves a lot like mercury but has significantly lower toxicity. Because of this, Galinstan is used as a replacement for mercury in a variety of applications.

In this post, I’m sharing the materials I created for an electrochemistry mini-unit that I used in my AP Chemistry interactive notebook. It’s important to note that you do not need to do interactive notebooking with your students to find some or all of these materials useful. I have included the following:

Gentle Reader, forgive me if the title - Connecting Acid-Base and Redox Connections (CABARC) - is redundant, but the connections between acid-base and redox reactions already exist, and it is my hope that we as instructors can parlay these connections into easier, better, and deeper understanding of both topics.

A classic chemistry experiment¹ involves using a concentrated solution of KNO₃ to “paint” a design in a continuous line on a piece of paper, allowing it to dry, and then igniting one end of the paper (Video 1).²
