Four substitutedcisandtrans-4,5-dihydroxyhexahydropyridazines that were expected to undergo pH induced conformational switching were synthesized and carefully investigated by NMR analyses and calculations. For two of the compounds a large difference in pKaexisted between the two possible chair conformers ...
pKa and pH - The fundamental distinction between pKa and pH is that pKa denotes an acid's dissociation, whereas pH denotes a system's acidity or alkalinity.
Consider the reaction between a weak acid (HA) and a weak base (B). If the pKa of HA was 4.8 and the pKa of BH+ was 10.3, what would be the value of the equilibrium constant? The ammonium ion (NH_4^+, pK_a = 9.25) has a lower pK_a than the methylammonium ion (CH_3NH_3...
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

There is a linear relationship between log P of the tested compounds and the logarithm of the molar micelle–water partition coefficient (log KMN). On the other hand molar solubilization capacities are nearly independent of log P. It is shown that the ability of Polysorbate...

Metal chelating ligands, which have a thioether-type sulfur group and an acidic group as coordination sites for metal ions, have been synthesized in order to investigate the relationship between the structure of the metal ligand and the extraction ability for "soft" metal ions, Ag(I), Hg(II)...
