Again, the book doesn’t give exact numbers for one of these molecules so just picking any number out of the relevant range is fine. pKeq = pKa (final base) – pKa(initial base)= 15.5 - 60 = -44.5 Keq = 10-pKeq = 10 44.5

It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid–base reactions. The chemical species HA is an acid that dissociates into A , the conjugate base of the acid and a hydro…

This experimental parameter is called "the pKa". The pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. The lower the pKa of a Bronsted acid, the … fresh chinese noodles for saleWebUse table search to locate desired compound in database.
