Question

state krichoff's law . How can it be used to calculate the dissasociation constant of weak electrolytes. (3 marks)​

Answer 1

Answer:

ANSWER

The molar conductivity  of weak electrolytes at infinite dilution cannot be 

determined experimentally, firstly because the conductance of such a solution is

low and secondly because dissociation of such an electrolytes is not  completed

even at high dilutions. 

The molar conductivity of such an electrolyte at infinite dilution can be 

calculated using Kohlrausch’s law.

Kohlrausch's law  states that the equivalent conductivity of an 

electrolyte at infinite dilution is equal to the sum of the 

conductances of the anions and cations. If a salt

is dissolved in water, the conductivity of the solution

is the sum of the conductances of the anions and cations.
