The conductivity of an ionic solution depends on: A. The nature of the electrolyte added Choose the correct answer from the options given below: |
B, C and D only A, B and C only A, C and E only B, D and E only |
A, C and E only |
The correct answer is Option (3) → A, C and E only. The conductivity of an ionic solution is influenced by several factors: A. The nature of the electrolyte added: Different electrolytes dissociate to varying extents in solution. Strong electrolytes (like NaCl) fully dissociate into ions, leading to higher conductivity, whereas weak electrolytes (like acetic acid) partially dissociate, resulting in lower conductivity. Therefore, the nature of the electrolyte has a significant impact on conductivity. B. The volume of the container: Conductivity does not directly depend on the volume of the container. It is a property related to the ions in the solution and their mobility, not the volume of the solution or the container itself. C. The size of the ions and their solvation: The size of the ions affects how easily they can move through the solution. Smaller ions tend to move more quickly, leading to higher conductivity. Solvation (hydration in water) also plays a role because highly solvated ions (ions surrounded by a layer of solvent molecules) move more slowly, reducing conductivity. D. Pressure: Pressure has little to no direct effect on the conductivity of an ionic solution under normal conditions, especially for aqueous solutions. E. The concentration of the electrolytes: Concentration plays a major role in conductivity. Initially, as the concentration of electrolytes increases, conductivity increases because more ions are available to carry the electric current. However, at very high concentrations, the conductivity might decrease due to ion pairing or limited mobility of ions. Conclusion: The nature of the electrolyte (A), the size of the ions and their solvation (C), and the concentration of the electrolytes (E) are the key factors influencing the conductivity of an ionic solution. Therefore, the correct set of factors is A, C, and E only. |
