Ka and Concentration

Postby Lily Guo 1D » Wed Dec 06, 2017 3:00 am

Is Ka the same thing as [H3O+]?

No, Ka is [H3O+][A-]/[HA-], so the products divided by the reactants for K!

No. Ka, the acidity constant, is the products/reactants. Ka= [H30+][A-]/[HA].

Ka is the acidity constant, or the equilibrium constant of an acid dissociation equation. It is a ratio of the products concentration to the reactants concentration. On the other hand, [H3O+] is the concentration of hydronium ions and is measured by pH.
