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 ...

Predict the pH of an aqueous solution during the titration of strong and weak acids and bases. -Understand buffer solutions and predict changes in pH of a buffer when an acid or base is added.

A titration experiment can be carried ... neutralisation reactions and can also be used to calculate an unknown concentration (of either the acid or alkali). When titrating, it is essential ...

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.
