Equivalent conductance of a week electrolyte at infinite dilution cannot be dilution cannot be directly measured. Why ? How is this calculated ?

The equivalent conductances of two strong electrolytes at infinite dilutution in H_2O ( where ion move freely through a solution ) at 25^(@)C are give below Lambda_(CH_3COONa)^(0) = 91.0 S cm^(2)//"equiv", Lambda_(HCl)^(0) = 426.2 S cm^(2)//"equiv" What additional information / quantity one needs to calculate Lambda^(0) of an aqueous solution of acetic acid ?

The correct order of equivalent conductance at infinite dilution of LiCI, NaCl. KC1 is

Why does the conductivity of a solution decrease with dilution ?

Why does the conductivity of a solution decrease with dilution?

Conductors allow the passage of electric current through them. Metallic and electrolytic are the two types of conductors. Current carriers in metallic and electrolytic conductors are free electrons and free ions respectively. Specific conductance or conductivity of the electrolyte solution is given by the following relation: K= cx (l)/(A) where, c=1/R is the conductance and 1/A is the cell constant, Molar conductance (^^_m) and equivalence conductance (^^_e) of an electrolyte solution are calculated using the following similar relations: ^^_m = K xx (1000)/(M) ^^_(e) = K xx (1000)/(N) where, M and N are the molarity and normality of the solution respectively. Molar conductance of strong electrolyte depends on concentration : ^^_m = ^^_m^(0) - b sqrt(C) ^^_m^(0) = molar conductance at infinite dilution C = concentration of the solution b = constant The degrees of dissociation of weak electrolytes are calculated as alpha = (^^_m)/(^^_m^(0)) = (^^_e)/(^^_e^(0)) Which of the following decreases on dilution of electrolytic solution?
