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 ...

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 ...

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 ...

Because of their reduced dimensions, higher integration density and mechanical flexibility, atomically thin 2D materials have the potential to change the configuration of future device architectures.

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 ...
