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 ...

Several theories have been developed to explain the behaviour of acids and bases. The most notable theories include the Arrhenius concept, the Brønsted-Lowry theory, and the Lewis concept. In the ...

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 ...

Chemists want to trick cancer cells into taking up drug molecules by attaching the payloads to fatty acids. These cells grow rapidly compared to normal cells and they recognize fatty acids as ...

Research into gas-phase Brønsted acids has yielded profound insights into proton donation processes devoid of solvation effects, allowing chemists to probe intrinsic acid strengths. This field ...
