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...
pka Table - pKa is an acid dissociation constant used to describe the acidity of a particular molecule. Its value is directly related to the structure of the given compound.
pKa
pKa - The pKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution. The quantitative behavior of acids and bases in solution can be understood only if their pKa values are known. To learn more about Calculation o
Similarly, the effective pK(a) value of the N-terminal PKA site mutant R2-S25A was 6.99 +/- 0.02 (n = 6). The effective pK(a) values of the two COOH-terminal PKA site mutant channels, however, were significantly shifted to alkaline values; i.e., 7.15 +/- 0.06 ...

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...
Calculate the concentration of hydrogen ions in an acetic acid solution given that the pKa = 4.76 and the ratio of [CH_3 COO^- ]/[CH_3 COOH] is 0.6. Break down the mathematical steps when you get ''4.53 = -\log(H^+)'' and the steps to the final answer of ...
