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 … WebWhat is pKa? In 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.
