This lab includes a demonstration of the proper use of a burette system for titrations ... buffer solution need to be weak (weak acid and weak base). The weak acid component neutralizes added base and ...

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 theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...
