The equivalent conductances of two strong electrolytes at infinite dilution in H2O (where ions move freely through a solution) at 25°C are given below:
Λo
CH3COONa = 91.0 S cm2 / equiv
Λo
CHCl = 426.2 S cm2 / equiv

Λ° of NaCl
Λ° of CH3COOK
The limiting equivalent conductance of H+ (λo
H+)
H+)
Λ° of chloroacetic acid (ClCH2COOH)
