Explore the concepts of pKa and pH values and how they relate to acids and bases. Learn the trends in pKa value for functional groups, acids, and...
valuePolyelectrolytesThe determination of pKa values of acids can be done in a multitude of manners, ranging from the classic potentiometric titration to computationally. We envisioned that it would be possible to determine the pKa values of polyelectrolytes using surface tension measurements at the ...
So if you have some water (pH = 7) and you then add some acetic acid, the pH value will drop, but so will the dissociation rate of the acid. So the acid kind of "undissociates" itself by lowering the pH value? And can you say that for all acids or bases, that they can be ...

Acidity constant of a weak acid.The partial dissociation of acid upon dissolution in the solvent is the major characteristics of a weak acid. pKa of acids defines the acidic strength in a given solution. It is a quantitative measurement.

Protein pKa calculations In computational biology, protein pKa calculations are used to estimate the pKa values of amino acids as they exist within proteins.
On the other hand, the pKa value is constant for each type of molecule. It is unaffected by concentration. Even a chemical ordinarily considered a base can have a pKa value because the terms "acids" and "bases" simply refer to whether a species will give up protons (acid) or remove the...
