conductometric titration

https://doi.org/10.1351/goldbook.09165
Titration in which the electric conductivity of a solution is measured as a function of the amount of titrant added.
Notes:
  1. The method is based on replacing an ionic species of the analyte with another species, corresponding to the titrant or the product with significantly different conductance.
  2. The equivalence-point is obtained as the intersection of linear parts of the conductance G, versus titrant volume V, curve (see figure).
  3. The method can be used for deeply coloured or turbid solutions. Acid-base and precipitation reactions are most frequently used.

Conductimetric titration curve of conductance (G) against volume of titrant. The end-point of the titration is indicated by a change in slope of the graph.
