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 ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...

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 ...

The process of carrying out a titration allows us to accurately measure the volumes of an acid and an alkali required for neutralisation. An indicator will be used to determine the exact volume ...
