Bestimmung der Konzentration von Reinigungsmitteln?
#39
Michaela schrieb:Ich habe nun endlich die Angaben zur

Konzentrationsbestimmung der Reinigungsmittelkonzentration per Titration bekommen. Bei dem

Alkalischen Reiniger steht nun:

pH-Wert 12,8 für eine 1 %ige Lsg. bei 20

°C
Dichte 1,14 g/cm3 bei 20 °C
Leitwert 5,53 mS/cm

für eine 1 %ige Lsg. bei 20 °C
P-Wert 2,0 ml 0,1 N HCl/10 ml 1%-ige

Lsg.
Titrierfaktor 0,50 Methode 1

Das Blöde ist nun das ich damit

leider nicht so viel anfangen kann, ich hätte eigentlich eher so etwas wie eine

Versuchsbeschreibung erwartet. Was ist denn zum Beispiel Methode 1 und welchen Indikator

benutze ich, in der Schule hatten wir da immer so etwas wie

Phenolphthalein.

Dein Reinigungsmittellieferant sollte Dir noch

eine Beschreibung der Titration "Methode 1" senden, die so ähnlich aussieht wie z.

B.

Michaela schrieb: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

0,22 wäre in diesem Beispiel der Titrierfaktor.
