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 ...

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 ...

ACE OF BASE A paper-based device titrates basic solutions of NaOH. The numbers at the end of each spoke indicate the concentrations of potassium hydrogen phthalate, which neutralizes NaOH, 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 ...

The petroleum industry relies on precise titration methods to analyze refined products, ensuring accurate energy and chemical production composition.

Many chemicals can be classified as being acidic, neutral or alkaline by using indicators. The pH scale is used to measure acidity and alkalinity. When an acid is neutralised, it forms a salt. Making ...

Titration is an analytical chemistry technique used to find the concentration of an unknown solution, using a solution whose concentration is known. The latter is called the titrant and is usually ...
