WebpKa. pK a is defined as the negative log 10 of the dissociation constant of an acid, its K a.Therefore, the pK a is a quantitative measure of how easily or how readily the acid gives up its proton [H +] in solution and thus a measure of the "strength" of the acid.Strong acids have a small pKa, weak acids have a larger pKa. The most common acid we will talk … WebThe value of the equilibrium constant is given by. Kb = [BH+][OH−] B. The greater the value of Kb, the stronger the base. For most weak acids, Kb ranges from 10−2 to 10−13. pKb = − logKb. For most weak acids, pKa ranges from 2 to 13. The smaller the value of pKb , the stronger the base. Here's a video on pKa and pKb.

WebpKa is a number that describes the acidity of a particular molecule. It measures the strength of an acid by how tightly a proton is held by a Bronsted acid. The lower the value of pKa, the stronger the acid and the greater its ability to donate its protons. describe the acidity of a particular molecule Ka denotes the acid dissociation constant.

WebVideo transcript. - [Voiceover] Let's look at how to use a pKa table. Remember from general chemistry that pKa is equal to the negative log of the Ka.
