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 ...
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 ...
To define "steady-state" chronic hypercapnia in man, we studied 20 patients with stable carbon dioxide tensions from 34 to 103 mm of mercury and with no apparent complicating disorders. The whole-body ...
