Hint: We know that the conductance is the measurement of the conductivity of an electrolytic solution. It directly depends on the concentration of electrolyte solution. More the concentration of electrolyte solution, the more is the conductance. Here electrolyte Potassium Chloride and its reaction with hydrated ferric oxide is related with conductance.
Complete answer:
Conductivity or conductance of an electrolytic solution is the measurement of the ability of a solution to conduct electricity. The specific conductance of an electrolytic solution depends upon the concentration of electrolyte. Basically the conductivity depends upon the nature of electrolyte. If the electrolyte is strong then it will fully dissociate into ions and if the electrolyte is weak then it will dissociate partially.
The strong electrolytes will have more conductivity as compared to weak electrolytes due to complete dissociation. Here, the molar conductance of potassium chloride is subtracted because molar conductance of potassium chloride is not asked i.e. to remove the potassium from potassium acetate and chlorine from hydrochloric acid. It is given in the question that the value of molar conductance of potassium acetate, hydrochloric acid and potassium chloride
When an electrolyte like \[KCl\] is added of \[Fe{{\left( OH \right)}_{3}}\] sol, the positively charged colloidal particles of \[Fe{{\left( OH \right)}_{3}}\] get coagulated by the oppositely charged \[C{{l}^{-}}\] ions provided by \[KCl\]
During the addition of silver nitrate in aqueous potassium chloride the chloride ions form the precipitate while the nitrate ions contribute to electrolytic solution so the overall conductance of the solution remains the same till the end point.
Note:
Remember that According to the theory of electrolysis, dissociation which was given by Arrhenius, if the electrolyte has completely dissociated then the value of molar conductance at infinite dilution will be minimum.
