State and explain Kohlrausch's law. How would you determine the molar conductance of a weak electrolyte at infinite dilution?

Text Solution

Verified by Experts

Kohlrausch.s law: It states that at infinite dilution, the molar conductance of an electrolyte is equal to the sum of molar conductance of its ions with Molar conductance of each ion multiplied with number of ions present in the formula of electrolyte. Eq `Lamda_(m)^(oo) (CH_(3)COOH)= lamda_(m)^(oo) (H^(+)) + lamda_(m)^(oo) (CH_(3)COO^(-))`
`Lamda_(m)^(oo) (NH_(4)OH)= lamda_(m)^(oo) (NH_(4)^(+)) + lamda_(m)^(oo) (OH^(-))`
