Easily convert pKa to Ka with our pKa to Ka Calculator, perfect for understanding acid strength in chemistry. 7 and the ka is 1. Any time you see a "p" in terms of acid-base chemistry, it automatically signifies -log (whatever is after p). 8 x 10 ^-16 Their explanation is that to get the Ka of pure water you take the Kw and divide it by the concentration of water which is 55. It measures the strength of an acid. At the half equivalence point [HA] = [A-] is still true, although [HA] is really [H3O+], because a defining characteristic of a strong acid is that it is stronger than the hydronium ion, which is the strongest acid that can exist in an Jan 2, 2007 · Ka is the only true "measurement". The acidity constant Ka is the equilibrium constant for dissociation of an acid into its conjugate base and H+. Includes chart, formula breakdown, and acid strength interpretation.
