Bestimmung der Konzentration von Reinigungsmitteln?
#1
Hallo zusammen,

wir werden in Zukunft ein

Gerät benutzen das unser Reinungsmittel automatisch in der richtigen Konzentration mit

Wasser mischt. Da man sich aber ja nicht nur auf Geräte verlassen sollte, würde ich die

Konzentration gerne mittels Titration ermitteln. Leider ist es jetzt 6 Jahre her das ich das

letzte Mal eine Titration durchgeführt habe.
Das einzige was ich zur Titration finden

konnte ist folgendes:

für die alkalischen Produkte:

10ml Anwendungslösung

werden nach Zusatz von 1-2 Tropfen Phenolphthalein-Lösung mit 0,1N Salzsäure bis zum

Farbumschlag von rot auf farblos titriert.

Verbrauchte ml 0,1N Salzsäure x 0,22 = %

Anwendungslösung

für die sauren Produkte:

10ml Anwendungslösung werden nach

Zusatz von 1-2 Tropfen Phenophthalein-Lösung mit 0,1N Natronlauge bis zum Farbumschlag von

farblos auf rot titriert.

Verbraucht ml Natronlauge x 0,130 = %

Anwendungslösung

Könnt ihr mir sagen ob meine Angaben zur Konzentrationsbestimmung

richtig sind ? <!-- sIcon_question: --><img src="{SMILIES_PATH}/icon_question.gif" alt="Icon_question:" title="Question" /><!-- sIcon_question: -->

Wie führt ihr Konzentrationsbestimmungen durch? <!-- sIcon_question: --><img src="{SMILIES_PATH}/icon_question.gif" alt="Icon_question:" title="Question" /><!-- sIcon_question: -->



Fragen über Fragen und ich hoffe ihr könnt mir weiterhelfen.
Gruß
Michaela

Das RICHTIG GROSSE Chaos erschaffe ich noch von Hand !
