Titration of a weak acid with a weak base with Cobra SMARTsense

Principle

in this experiment, the concentration of an acetic acid solution is determined using a potentiometric titration. In doing so, the students examine the recorded titration curve for characteristic features and determine the equivalence point via a suitable indicator (here: phenolphthalein).

Benefits

• Experiment is part of a complete solution with numerous experiments from the field of titration and ion detection, simple structure of a teaching series

• In addition to the graphical display of the measurement data on the measuring instrument, all data can also be transferred to a computer for evaluation

• Experimental literature available for students and teachers: minimum preparation time
• Risk assessment available for students and teachers
• Easy teaching and efficient learning when using the available interactive experimental literature
