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 ...

The acid dissociation constant, K a, and its negative decadic log, pK a, are key life sciences parameters that describe molecular acidity. Specifically, these values indicate the protonation state of ...

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 ...
