How is conductivity affected with dilution?

Conductivity changes with the concentration of the electrolyte. On dilution as volume of solution increases. Thus, the number of ions per ml decreases and hence conductivity decreases. The equivalent conductivity and molar conductivity increases with dilution.

What is the effect of dilution on conductivity and molar conductivity of a solution Class 12?

Due to dilution, the volume of solution increases and there is increase in the number of ions. But number of ions per c.c. of solution decreases. This is the reason that specific conductivity of solution decreases on dilution. The molar conductivity of solution increases upon dilution.

How does conductivity vary with dilution 12?

With dilution, the ions go far apart from one another and inter-ionic forces decreases. Therefore, molar conductance increases with dilution.

What is the unit of equivalent conductance?

Unit of Equivalent conduction is Equiv-1 . cm2 . ohm-1 . 1 mho = 1 ohm-1.

Why does conductivity decrease with dilution?

Conductivity of a solution is the conductance of ions present in a unit volume of the solution. On dilution the number of ions per unit volume decreases. Hence, the conductivity decreases.

What is the effect of dilution on conductivity and molar conductivity of weak and strong electrolytes?

When the solution is dilute the number of ions available per unit volume reduces, resulting in the reduction of the conductivity. The molar conductivity of both weak and strong electrolytes increases with a decrease in concentration or dilution.

How does conductivity varies with dilution for a strong electrolyte?

The molar conductivity of both, strong and weak electrolytes increases with dilution or the decrease in concentration of the electrolytic solution. As the dilution increase , the dissociation of the electrolyte increases, hence the total number of ions increases, therefore, the molar conductivity increases.

Why does equivalent conductance increase with dilution?

The equivalent conductance of strong electrolyte is increased by dilution, because its value is equal to the multiple of Kυ and the volume of solution. By making dilution the volume of solution increases which also increase the value of equivalent conductivity.

What are the units of conductivity and equivalent conductivity?

The unit of conductivity is $S/m$ or $S/cm$. Now, we know that one gram equivalent of a substance is the number of gram equivalents per unit volume.

What is the effect of decrease in concentration on conductivity and molar conductivity?

Change in Molar Conductivity Molar conductivity increases with a decrease in concentration. This happens because the total volume, V, of the solution containing one mole of electrolyte also increases. Upon dilution, the concentration decreases.

How does the conductivity varies with dilution for a strong electrolyte?

Electrolytic conductance decreases with increase in concentration or increases with increase in dilution. The greater the number of ions, the greater is the conductance.As with dilution, more ions are produced in solution so conductance also increases on dilution.

How does conductivity and molar conductivity vary with dilution?

Upon dilution, specific conductance or conductivity decreases while molar conductivity increases. Conductivity is the conductance of one centimeter cube of the solution. Upon diluting the solution, the concentration of ions per centimeter cube decreases and therefore, the conductivity decreases.
