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 ...

The Real-Time pH Process Modeling and Control Simulation Software is built in National Instruments' LabVIEW platform and includes pH process diagram, a strong-acid-strong-base pH model, a ...
