This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

The acid dissociation constant, K a, and its negative decadic log, pK a, are key life sciences parameters that describe molecular acidity. Specifically, these values indicate the protonation state of ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...
