Zadanie 20.

Na calkowite stezenie kationow H,O° w wodnym roztworze kwasu sarkowego(VI) sklada sie suma

steen tych kationów powstalych w pierwszym etapie dysocjaci oraz w drugim etapie dysocjacji:

[HO'%a, = [H50'7, + 1H50%.

H,SO, + HO -, HSO; + H,0* (H507,

HSO: + HO = SO? + H,0*

[H.07

Pierwszy etap dysocjacji kwasu siarkowego(VI) jest praktycznie calkowity, wiec stezenie kationów

H.O° powstajacych w tym etapie jest röwne stezeniu tego kwasu:

[HO'7, = co.
