Question
Explain about the factors affecting electrolytic conductance. Conductivily Cell
✓

Answer

  1. If the interionic attraction between the oppositely charged ions ofsolute increases, the conductance will decrease.
  2. Solvent of high dielectric constant show high conductance in solution.
  3. Conductance is inversely proportional to the viscosity of the medium. i.e., conductivity increases with the decrease in viscosity.
  4. If the temperature of the electrolytic solution increases, conductance also increases.
  5. Molar conductance of a solution increases with increase in dilution. This is because, for a strong electrolyte, inter ionic force of attraction decrease with dilution.
  6. For a weak electrolyte, degree of dissociation increases with dilution.
