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.
