This educational film explores acid-base indicators and their color changes in response to acidity. It demonstrates how substances like tea, red cabbage, and litmus paper react when acids are added, ...

Acid/base indicators are described and used to identify substances as acids or bases. Indicators and the pH Scale: Acid/base indicators are described and used to identify substances as acids or bases.

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 ...
