Webpka file description. File extension pka is traditionally associated with the PKarc compression utility and used for one of its default compressed archives. PKarc was released in the mid-1980s in addition to duplicating the compression techniques used in ARC, added an additional algorithm which produced smaller files. Created by Phillip Walter ... WebIn simple terms, pKa is a number that shows how weak or strong an acid is. A strong acid will have a pKa of less than zero. More precisely – pKa is the negative log base ten of the Ka value (acid dissociation constant). It measures the strength of an acid — how tightly a proton is held by a Bronsted acid.

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.
