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 ...

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 new study has been regarded as "very important" because it offers a new framework for understanding reactions in organic chemistry. In their study, the team addressed the cooperative role of ...

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 ...

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 ...

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 ...

Neutralisation is the reaction of an acid with a base that results in the pH moving towards 7. It is a useful process that occurs in everyday life such as in the treatment of acid indigestion and the ...
