Question

write the expression for the molar conductivity.How kohlraush law is useful in obtainig molar conductivity at zero concentration of weak electrolyte? explain​

Answer 1

Answer:

Solution :

Statement of Kohlrausch's law : This states that at infinite dilution of the solution, each ion of an electrolyte migrates indepef!dently of its co-ions and contributes independently to the total molar conductivity of the electrolyte, irrespective of the nature of other ions present in the solution <br> This law of independent migration of ions is represented as <br>

. <br> Where

is the molar conductivity of the electrolyte at infinite dilution or zero concentration while

and

are the molar ionic conductivites of cation and anion respectively at infinte dilution.

Explanation:

so this is your answer by

Answer 2

Answer:

Kohlraush law :

The limatating molar conductivity of the solution is directly propotional to sum of the independent contributions of anion and cation present in the electrolyte.

Application :

To find the limatating molar conductivity of week and strong electrolyte
