The pH scale is used to measure acidity and alkalinity levels. It measures the presence of positively and negatively charged hydrogen ions in a particular solution. The higher the hydrogen ions, the ...

Your body is constantly performing a delicate balancing act that most of us never think about. While we’re busy worrying about calories and carbs, a microscopic chemistry experiment determines how ...

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 ...

THE evaluation of any acid–base disturbance requires a knowledge of the expected degree of compensation for a primary disorder of any specified magnitude. The most logical approach to this problem is ...

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 ...
