Which of the following statements is INCORRECT? The conductivity of electrolytic (ionic) solutions depends on:

The correct answer is Option 1.

Key Points

• The conductivity of electrolytic solutions primarily depends on the nature of the electrolyte added, not on the nature of the solute and its viscosity.
• Electrolyte concentration affects the number of ions in the solution, which in turn influences conductivity.
• The size of the ions produced and their solvation significantly impact the mobility of ions, thus affecting conductivity.
• Viscosity influences the movement of ions but is not directly related to the nature of the solute.

Additional Information

• Electrolytic Conductivity:
  • Electrolytic conductivity is a measure of a solution's ability to conduct electricity.
  • It is influenced by the presence and concentration of ions in the solution.
  • Conductivity increases with the number of ions present.
• Ion Mobility:
  • Ion mobility refers to the speed at which ions move through a solution under the influence of an electric field.
  • Higher ion mobility leads to higher conductivity.
• Solvation:
  • Solvation is the process of surrounding solute particles with solvent molecules.
  • It affects ion size and mobility, thus impacting the conductivity.
• Viscosity:
  • Viscosity is a measure of a fluid's resistance to flow.
  • Higher viscosity can slow down ion movement, affecting conductivity.
  • However, it is the nature of the electrolyte that directly influences conductivity, not just viscosity.
