Answer:
There is sharp increase in the number of ions in the solution. Hence, the molar conductivity of a weak electrolyte rises steeply at low concentration. (ii) Strong electrolytes: The molar conductivity of a strong electrolyte decreases slightly with the increase in concentration.
Answer:
On increasing dilution molar conductivity of strong electrolyte and weak electrolyte increases therefore on increasing concentration molar conductivity will decrease.
Limiting Molar conductivity
Limiting Molar conductivity =
[tex]\frac{conductivity}{molarity} \times 1000[/tex]
unit of molar conductivity
[tex]s \: {cm }^{2} {mol}^{ - 1} [/tex]
hope it helps
