  • Stuck here, help me understand: An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to:

An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to:

  • Option 1)

    Increase in ionic mobility of ions

  • Option 2)

    100% ionisation of electrolyte at normal dilution

  • Option 3)

    increase in both i.e. number of ions and ionic mobility of ions

  • Option 4)

    Increase in number of ions

 

Answers (1)

 

Conductivity of electrolyte -

It depends on:

1. The nature of electrolyte

2. Size of ions

3. Nature of solvent and its viscosity

4. Concentration of the electrolyte

5. Temperature

-

 

 

Variation of Molar Conductivity in strong electrolyte -

\Lambda m=\Lambda^{0} m-AC^{\frac{1}{2}}

- wherein

For strong electrolyte, \Lambda m increases slowly with dilution.

 

 Increase in equivalent conductance of a strong electrolyte is mainly due to 

- Increase in ionic mobility of ions.
