Conductometric Titration

Lab Summary

Use a conductivity sensor and drop counter to determine the concentration of a solution with titration.

Theory

Students determine the titration equivalence point with a conductometric titration method.

Method

Students gain experience conducting the following procedures:

  • Using a conductivity sensor and drop counter to perform titration measurements.
  • Determining equivalence points and solution concentrations.

Sensors / Equipment Used:

PASPORT Conductivity Sensor

(PS-2116A)

Utilizes platinum probes for greater range and improved accuracy in high & low concentrations.
