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 ...

pH is a measure of a solution's acidity or alkalinity. Acids have a pH below 7, releasing hydrogen ions when dissolved in water, while bases have a pH above 7, releasing hydroxide ions. Enzymes have ...

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 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 ...

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 review describes a method of analyzing acid–base disorders that incorporates insights from the traditional, bicarbonate-centered model and the Stewart (or strong ion) model (Table 1). 1–6 ...
