Lösung: Be HX an acid which reacts with water, so that it can be made by means of chemical balance define as follows: K=(c[H3O+] · c[X–])/(c[H2O · c[HX]) It can also be further simplified by Water concentration approx. 1000 is greater than an acid: KS= (c[H3O+] · c[X–])/(c[HX]) . Instead of the KS Value is also derived from KW It's worth it.
A substance which thus releases its protons (in water) would have a high KW-Wert and Again, the numbers are small, so the logarithm (negative decimal) is taken again: pKS = -log(Ks). Quintessence: the pKS corresponds to the willingness to pay of H+ (Protons) of a compound.
