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 ...

Students will become familiar with the equipment and procedures used during general titrations ... The weak acid component neutralizes added base and the weak basic component neutralizes added acid.

This means that the pH values of strong acids are lower than that of weak acids, which explains why the rate of reaction of strong acids with substances (such as metals, metal carbonates etc ...

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.
