conductometric titration
Quick Summary
Conductometric titration is a chemical analysis technique that measures the electrical conductance of a solution to determine the concentration of an analyte. This method is part of electroanalysis, which uses electrodes to measure electrical properties of a solution.1
In conductometry, the ability of a solution to conduct an electric current is monitored. This conductance depends on the presence and type of ions in the solution, as ions are responsible for carrying the current. Generally, smaller and more highly charged ions conduct better than larger or less charged ions.1
Conductometry is particularly useful for determining the end points of titrations that involve ions. A conductometric titration curve is created by plotting conductance against the volume of titrant added. The intersection of extrapolated linear regions on this curve indicates the end point of the titration. This method is not selective for qualitative analysis as all ions contribute to conductivity.12
