What does Ka represent and why is it significant?

Ka is an acid dissociation constant that is a quantitative measure of the strength of an acid in solution.

Hello,
Ka is essentially a measure of how strong an acid is in a solution. It is equal to ([A-][H+])/[AH].
Hope this helps!

Ka is the ratio of the forward reaction to the backward reaction. It is important because for weak acids, compounds only partially dissociate into H+ ions, and there is a reverse reaction with the equilibrium constant, k.

HA <--> H+ + A-

ka = [H+][A-]/[HA]

Ka (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid–base reactions.

It is a constant that measures how strongly the acid dissociates, meaning how easily it donates a proton.
