Question

degree of dissociation of pure water is 1.9×10^-9 molar ionic conductance of h + and oh - ions at infinite dilution are 200s cm^2 mol-1 and 350s cm2 mol- respectively molar inductance of water is​

Answer 1

Answer:

The answer is 1.045 x 10^-6 Scm^2 mol-1

Explanation:

Degree of dissociation of pure water ( ∝) =  Λm /  Λm ∞  

Molar ionic conductance of water  Λm ∞  (H2O) = Λm ∞ (H+) + Λm ∞ (OH-)

                                            = 200 cm^2 mol-1 + 350 cm^2 mol-1  

                                            = 550 Scm^2 mol-1  

We know that: Degree of dissociation of pure water is 1.9×10^-9

Thus the molar inductance of water is​

1.9×10^-9 x 550 Scm^2 mol-1 = 1.045 x 10^-6 Scm^2 mol-1 .
