der pH-Wert in Laken
#1
Hallo

Schon wieder aus der Laborwelt…

Einer meiner Kunden stellt

würzmittel für Kochpökelprodukte her.
Und vor Auslieferung wird immer eine Untersuchung

des pH-Wertes der herzustellenden Anwendungslösung durchgeführt.

1. wie weit ist

es üblich, das bei gleicher Rezeptur der pH-Wert in der Anwendungslake schwankt?
2.

Üblicherweise schwankt der pH-Wert von Charge zu Charge um ca. 0,2 bis 0,3. Ist das im guten

/ üblichen Bereich
3. wie wirk sich Phosphat in der der lake aus? Hebt oder senkt

die anwesendheit von Phosphat den pH-Wert?

Warum war ich in der Chemie-Vorlesung nur

immer mit anderen Dingen beschäftigt?
Danke für Eure Unterstützung

Ariane
