Kohlrausch's law states that at:
- AFor strong electrolyte,molar conductance varies linearly with concentration of electrolyte.
- BInfinite dilution,each ion makes definite contribution to molar conductance of an electrolyte whatever be the nature of the other ion of the electrolyte.
- CAt all concentration,each ion makes definite contribution to molar conductance of an electrolyte whatever be the nature of the other ion of the electrolyte.
- DMolar conductance increases with decrease in concentration.
