Q

Bestimme die Maximale menge eines stoffes die sich in wasser lösen kann
Mit dem pKl wert

A

pKl gegeben x,y aus Natürlichen Zahlen
HxAy(s)<=> x(H^+)(aq)+y(A^-)(aq)
die Konzentration der produkte umstellen
x* c(H^+)=y* c(A^-) => c(H^+) =(x/y)c(A^-)
Kl(HxAy) = (c(H^+)^x)(c(A^-)^y)
=( ((x/y)c(A^-))^x)
(c(A^-)^y)
nach c(A^-) umstellen und denn durch y teilen und fertig
