WebMay 25, 2024 · The acid dissociation constant is the equilibrium constant of the dissociation reaction of an acid and is denoted by K a. This equilibrium constant is a quantitative measure of the strength of an acid in a solution. K a is commonly expressed in units of mol/L. There are tables of acid dissociation constants, for easy reference. WebpKb is the criterion used to estimate the alkalinity of the molecule. It is used to measure basic strength. The lesser the pKb is, the more potent the base will be. It is equivalent to …

WebSep 4, 2024 · September 4, 2024 by Alexander Johnson. The pKa and pKb scales are used to compare the strength of acids and bases. Acid dissociations are given a pKa value. For dissociation of bases, pKb is used. pKa and pKb differ in that pKa is the negative logarithm of Ka, whereas pKb is the negative logarithm of Kb. Table of Contents show.

WebFeb 8, 2013 · pKa > 14 just means it's a really weak acid or very strong base. In an acid dissociation reaction, you'll see a large pKa if the Ka is small (pKa = -log (Ka) ), which means that the acid doesn't dissociate well. It would probably need a very strong base to dissociate but generally, it just means a very weak acid. 0 milski 1K member 5+ Year Member
