Factors Affecting Conductivity

Factors Affecting Conductivity

Ohm's law can be easily defined as conductivity by V = IR, where V is the voltage across the sample, Y is the current, and R is the resistance. The behavior determines the ability of the material to conduct electricity.

Factors that affect conductivity measurements are listed below.

Ion size:

If the size of the ion increases, the conductivity also increases, since it is inversely proportional to the size of the ions.

The concentration of the solution shows:

As the concentration of the sample solution increases, conductivity can be reduced because it is inversely proportional to conductivity; therefore, conductivity measurement requires a dilute sample solution.

Nature of the electrolyte:

Strong electrolytes completely dissociate into ions, therefore the conductance of solutions is high.

Number of ions present in the sample solution:

It generally depends on the dissolution of the sample into ions. The amount of ions in solution is specifically related to conductance.

Temperature:

The conductivity of the electrolyte increases with increasing temperature. This is due to the mobility of ions to increase in temperature.

The charge of the ions:

The conductivity of the sample solution decreases on positively charged ions and negatively charged ions increase the conductivity.
