Question

For what purpose is a conductivity cell used?

Answer 1

A conductivity cell is used to measure the electrical conductivity of an electrolytic solution. The main purposes of using a conductivity cell are:

1. To determine the conductance (or conductivity) of a solution, which indicates how well it can conduct electricity due to the presence of ions.
2. To study the variation of conductivity with concentration, helping in the analysis of strong and weak electrolytes.
3. To measure molar conductivity and equivalent conductivity, which are important in electrochemistry.
4. To perform titrations involving ionic compounds, where changes in conductivity help detect the equivalence point.
