Question

The molar conductivities of KOAc and HCl at infinite dilution in water at 25˚C are 90.0 and 426.2 S cm² mol⁻¹, respectively. To calculate the molar conductivity of HOAc at infinite dilution, the additional molar conductivity value of which one of the following electrolytes will be required?

Vimal Swarnkar · Accepted Answer

(b) KCl. Λ°(HOAc) = Λ°(KOAc) + Λ°(HCl) − Λ°(KCl). K⁺ and Cl⁻ cancel. So KCl value is needed → (b).

Answer

(a) NaCl

Answer

(c) KNO₃

Answer

(d) NaOH
