Question

Huckel theory of strong electrolytes, increase in conductivity on
According to Debye
dilution is due to:

A) Increase in number of ions

B) Increase in the mobility of ions

C) Decrease in the no. of ions
D) Decrease in the mobility of ions

Answer 1

Explanation:- We know that according to Debye Huckel rule, on dilution the ionization of strong acid increases due to increasing volume. Since, ionic mobility also increases. Therefore, the conductivity of strong electrolyte increases on dilution slightly.

Answer 2

Answer:

According to Debye dilution is due to Increase in the mobility of ions

Explanation:

• We are aware that the Debye Huckel rule states that strong acid ionization rises with volume on dilution.
• Strong electrolyte's conductivity marginally increases with dilution.

Debye huckel theory of strong electrolytes:

• At dilution, any strong electrolyte is practically entirely ionised.
• The electrolytic solution's cations and anions are not distributed equally.
• The core ion's net charge and the charge on the ionic environment are equal, but in the opposite directions.
• The interaction of the core ion with the surrounding ions in an electrolyte determines its properties.
• Because of stronger interionic attraction, the analogous conductance decreases with concentration due to a reduction in ionic mobility.
• Strong electrolytes are entirely neutral and dissocial . It provides a theoretical justification for how strong electrolyte solutions deviate from ideality.
