A crash course on the basic differences between acids and bases. A crash course on the basic differences between acids and bases, complete with a classroom-friendly experiment demonstrating the ...
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 ...
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 demonstration of the proper use of a burette system for titrations; including a detailed description, instructional video, and opportunity for students to collect data to ...
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 ...
The pH of your stomach acid can vary due to health conditions, medications, and other factors. Having a pH that is too high or too low can cause complications. Stomach acid, or gastric acid, is a ...
A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

Introduction Did you know that the juices in your stomach are nearly as acidic as lemon juice? Fortunately, your stomach has special cells that act as a barrier to the acid, preventing it from ...
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 ...
