Question

electrolyte	KCl	KNO3	HCl	NaOAC	NaCl
Δ (S cm2 mol-1)	149.9	145.0	426.2	91.0	126.5

Calculate A⁰_HOAC using appropriate molar conductances of the electrolytes listed above at infinite dilution in water at 25°C.

(a) 517.2 

(b) 552.7 

(c) 390.7 

(d) 217.5

Answer 1

(c) 390.7

(426.2 + 91) – (126.5) = 390.7
