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 ...

Capillary electrophoresis (CE) is a versatile and automated separation technique that exploits the differential migration of charged analytes under an applied electric field, thereby providing rapid ...

THE hydroxycarboxylic acids form very stable complexes with metal ions. In alkaline solution, both the carboxylic and the alcoholic hydroxyl groups take part in complex formation. For the calculation ...

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 isoelectric point (pI) is the point at which the net charge on a molecule is zero. pI is most commonly examined for proteins. Each of the amino acids in a protein carries a distinct charge, and ...
