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 ...

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 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, ...

Discover how red cabbage can act as a natural pH indicator, revealing whether substances are acids or bases through beautiful color changes. pH is a measure that tells us how acidic or basic a ...
