•
Pour 20 ml of the diluted (1:10) household vine-
gar into the beaker.
•
Immerse the pH-electrode (after thorough clean-
ing) in the vinegar solution, all the way to the
bottom of the beaker.
•
Select the analogue input A on the 3B NETlog
TM
and activate the experiment (template) for the de-
termination of titration curves in the 3B NETlab
TM
software; here, all necessary output adjustments
can be found.
•
Conduct and analyse the experiment.
