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, ...

I’m sure many of you reading this can remember your first acid-base titrations in chemistry class—the thrill of watching the pH indicator change color, and the fear of opening the stopper too much and ...

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 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 ...

Each chemical reaction involves an enthalpy change that leads to a change in temperature. The amount of substance converted during the reaction determines the increase (i.e. exothermic reaction) or ...

Titration is an analytical method frequently used within the industry. Manual, semi-automated, and fully automated titrations are popular options and are discussed in-depth in many academic studies.
