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 … WebMar 13, 2024 · Working with such numbers is inconvenient, so to makes things easier, chemists have defined the pKa number as: pKa = -log Ka.
