Factors affecting conductivity

Ohm's law can be defined as the conductivity easily by the V= IR, Where V the voltage there in the sample, I the current, and R are the resistance.  Conduct determines the ability of the material to conduct the electricity.

Factors affecting the conductivity measurements are mentioned as follows.

Size of the ions:

If the size of the ion increases the conductivity also increases, due to its inversely proportional to the size of the ions.

The concentration of the sample solution:

When the concentration of sample solution increases, the conductance can be decreased due to it is inversely proportional to the conductivity; therefore the conductivity measurement requires a diluted sample solution.

Nature of electrolyte:

Strong electrolytes totally dissociate into ions, consequently, the conductance of the solutions have high.

Number ions present in the sample solution:

It generally depends on the dissolution of the sample in ions. The quantity of ions in solution is specifically relative to the conductance.

Temperature:

The conductivity of the electrolyte increases when the temperature rises. This is due to ion mobility by raise the temperature.

The charge of the ions:

The conductivity of the sample solution decreases in positive charge ions and negatively charged ions increase the conductivity.
