Question

The mathematical expression for law of independent migration of ions and Ostwald's dilution law are given by:

• A. $\wedge ={\wedge }_m^0-B{C}^{1/2}$
• B. ${\wedge }_0=F(U_{+}+U_{-})$
• C. ${\wedge }_m^0=V_{+}{\lambda }_{+}+V_{-}{\lambda }_{-}$
• D. $\frac{{\wedge }_0}{{\wedge }_m}=\frac{1}{{\wedge }_m^0}+\frac{\wedge {{}_m}^c}{K_a({\wedge }_m^0{)}^2}$

Answer 1

The correct option is C ${\wedge }_m^0=V_{+}{\lambda }_{+}+V_{-}{\lambda }_{-}$

The molar conductance of an electrolyte at infinite dilution is equal to the sum of the contributions of the molar conductances of the cation and anion.

Hence, option C is correct.
