Why molar conductivity increases with dilution but conductivity decreases with dilution?
Thus it depends upon concentration of the solution. As volume increases on dilution, therefore no. of ions per unit volume carrying the current decreases. Therefore on dilution molar conductivity increases.
What is the variation of molar conductance with dilution?
On dilution, conductivity decreases but volume containing one mole of an electrolyte increases. The increase in volume on dilution is much more than the decrease in conductivity. As a result molar conductivity increases with dilution.
What is the effect of dilution on the specific conductivity and molar conductivity?
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.
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.
Why does the specific conductance decreases and equivalent conductance increases with dilution of a solution of electrolyte?
“Specific conductance” is the conductance due to unit volume (1 cc) of the solution. When the solution becomes dilute (concentration decreases), there will be lesser number of ions in unit volume of the solution. Therefore conduction decreases as the solution becomes more dilute as per reason (1) given above.
Is specific conductance increases with dilution?
Specific conductance decreases with dilution whereas equivalent conductance increases.
Why does equivalent conductance increases with dilution?
Equivalent conductance increases with dilution, because it is the product of specific conductivity and the volume V, containing one mole of electrolyte. Although, specific conductivity decreases with dilution, this decrease is compensated by the increasing value of the volume.
Why molar conductance increases with dilution?
On dilution as volume of solution increases. Thus, the number of ions per ml decreases and hence conductivity decreases. Molar conductivity is defined for 1 mole of ions. Thus on dilution, ions get more apart and mobility of ions increases which leads to increase in molar conductivity of the solution.
Does specific conductance increases with dilution?
How does specific conductance and equivalent conductance vary with dilution?
Why does molar conductance increases with dilution?
Molar conductance is dependent on the concentration of the electrolyte. When the solution is dilute the number of ions available per unit volume reduces, resulting in the reduction of the conductivity. These active ions impart more conductivity. …
