pH of a Dilute Acid
Use the sliders to select values for the pKs and the molarity of the acid.Ks is the ionic product of the solvent, Kw for water, with pKw=14.0.
The pH of the solution is displayed. The default values are for 0.1M ethanoic (acetic) acid in water at 25C.
(The values are only approximate, especially for more concentrated solutions, since activities are not taken into account.)
