Question

What is conductivity cell?

Answer 1

1. The glass apparatus used for measuring the resistance of a definite volume of a solution is called a conductivity cell.
2. It is made of Pyrex glass and is fitted with two platinum electrodes fixed at a certain distance from each other.
3. The reciprocal of a solution’s resistance is its conductance. Therefore, a solution’s resistance can be used to determine its electrolytic conductivity. 
4. A Wheatstone bridge and a special type of cell called a conductivity cell are used to measure the resistance of an electrolytic solution.
