Which of the following expressions indicates the correct relationship between molar conductivity of strong electrolyte and its concentration?
Options
- A= ₀ + c
- B= ₀ - a c
- C= ₀ + a c
- D= ₀ - c
Correct answer
B. = ₀ - a c
Step-by-step solution
The relationship between molar conductivity ( ) and concentration ( c ) for a strong electrolyte is given by the Debye-Huckel-Onsager equation. The equation is = ₀ - a c , where ₀ is the limiting molar conductivity at infinite dilution and a is a constant that depends on the nature of the electrolyte, solvent, and temperature. Answer: = ₀ - a c
