WebThe acid dissociation constant (Ka) is used to distinguish strong acids from weak acids. Strong acids have exceptionally high Ka values. The Ka value is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates. Thus, strong acids must dissociate more in water. WebOct 25, 2024 · Ka ()—the acid dissociation constant—tells you the strength of an acid in a different and more specific way than the better-known pH.Because Ka produces extremely wide-ranging values, pKa ()—the negative logarithm (base 10) of Ka—is often used to simplify the range of acid strength values.If all of this is twisting your brain a little, here’s …
