5.3.3Smart behavior of alginates The pKavalues for –COOH groups in M and G are 3.38 and 3.65, respectively. This results in precipitation of the soluble polymer below pH 2. However, most of the applications of alginate arise from the fact that it forms insoluble gels/precipitates withdivale...
The pKa of COOH, or a carboxylic acid group, is between 3 and 5. Carboxylic acids have a low pKa due to resonant structures, and it can be lowered more through the inductive effect. Is a high pKa acidic or basic? A large pKa value usually means that a molecule is basic. A solution...
Starting with the respective acid forms and increasing the pH value by adding NaOH portions FTIR spectra of PA and PAA show decrease of ν(CO) band due to carboxyl (COOH) groups and increase of νa(COO) band due to carboxylate (COO) groups. From the integrated band areas A the ...

Abstract:The solubility in different solvents, the oil/water detached coefficient and pKa value of baicalin were determined by UV spectrophotometry for the study of its absorption in vivo. The results showed that the higher solubility values of baicalin were 1 569 μg/mL and 1 458 μg/mL in...
