Acid–base titration is more than just mixing acids and bases — it’s a precise method to uncover unknown concentrations and chemical constants like pKa. By tracking pH changes as titrant is added, ...

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 ...

Strong base is added to three different buffers and water and the effect on pH is observed.

What buffers do: Buffers limit pH changes by using a weak acid and conjugate base pair to neutralize added acids or bases through reversible reactions. Why pKa matters: A buffer’s pKa determines the ...

This lab includes the complete titration procedure used to investigate how well a buffer resists changes in pH. Prepare a buffer solution by accurately calculating and measuring the required amounts ...

One of the ways that per- and polyfluoroalkyl substances (PFAS) earn their “forever chemical” nickname and persist in the environment is their acidity. Many of these toxic chemicals are highly acidic, ...
