LÖSLICHKEITSPRODUKT-KONSTANTEN
Das Löslichkeitsprodukt KL eines schwerlöslichen Salzes ist das Produkt aus der molaren Konzentration der einzelnen Ionen in einer gesättigten Lösung.
Für ein Festes Salz AaBb in Kontakt mit seiner gesättigten Lösung gilt allgemein:
AaBb(s) → aA+ + bB
Löslichkeitskonstante ist
KL(AaBb) = [A+]a∙[B-]b
Das Löslichkeitsprodukt ist wie alle Gleichgewichtskonstanten temperaturabhängig. Je geringer die Löslichkeit einer Substanz, umso kleiner ist ihr Löslichkeitsprodukt.
