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 ...

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 ...

In this video, we explore the fundamental role of electrons in chemical reactions, rooted in quantum physics and the ...

This lab includes the complete titration procedure used to investigate how well a buffer resists changes in pH. Prepare a buffer solution by accurately calculating and measuring the required amounts ...

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 ...
