The electric conductivity of aqueous electrolyte solutions is
determined by the type and number of charge carriers at constant
temperature. Characteristic changes in conductivity are connected
with changes in the ionic composition of reacting systems. These
can be used in the conductiometric titration as end point
- Drop counter optimizes the experimental procedure
- Accurate results by conductivity probe with integrated sensor Pt 1000
- Simplified implementation: all pre-settings already prepared
Using the Cobra4 system, measure the change in conductivity in
the titrations of the following:
- approximately 0.1 molar barium hydroxide solution with 0.1
molar sulphuric acid.
- approximately 0.1 molar hydrochloric acid with 0.1 molar sodium
- approximately 0.1 molar acetic acid with 0.1 molar sodium
Other samples can alternatively be set in advance for
conductiometric determination of their concentration contents.
