Acid Dissociation Constant Definition: Ka - ThoughtCo

WebJan 22, 2024 · Ka is the value that we equate to the dissociation of a weak acid into solution. As a Ka value increases, we can say that a compound is more acidic, whereas if this value decreases, we would say it is less acidic. A strong acid on the other hand is assumed to dissociate completely. Top danielle05 Posts: 50 Joined: Tue Jan 04, 2024 5:19 am WebClearly, ka =/ 1/Kb : one has H3O+ and the other has OH- (the others are in the equation, but in very very very small quatities so we ignore them) For example, HCN is an acid and CN- … software hba
