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 ...

In a titration, sulfuric acid of concentration \(0.1 moll^{-1}\) was added from a burette into a conical flask containing \(20cm^{3}\) of sodium hydroxide solution. The average titre was \(11.2cm ...

Acid/base titrations Grading: Your final grade for Chem 31 will be based 55 % on the lecture, and 45% on the laboratory. The grading scale may be adjusted downward to increase the overall average ...

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.
