Table of pka values of acids

WebApr 26, 2015 · If you look at a molecule like Sulfuric acid, H2SO4, a molecule with more than one acidic hydrogen, it's going to have two pKa's, one for each proton. In these cases, you can avoid confusion if you talk about the pKa of the proton instead of the pKa of the … WebWe use the acid dissociation constants (K a values) for this purpose. By the definition, the dissociation constant for an acid equals to the ratio of the product concentrations over …

WebThe greater is the value of p K a, the weaker will be the acid and the stronger its conjugate base. The greater is the value of p H ∗, the weaker will be the acid and the stronger will be the base. For acids, p H < 7 and for bases, p H > 7. The greater is the value of K b, the stronger will be the base and the weaker its conjugate acid.

WebThe values of \(pK_a\) and \(pK_b\) are given for several common acids and bases in Table 16.5.1 and Table 16.5.2, respectively, and a more extensive set of data is provided in Tables E1 and E2. Because of the use of negative logarithms, smaller values of \(pK_a\) correspond to larger acid ionization constants and hence stronger acids. declining healthcareWebThe table below contains the pKa values of four weak acids.
