The equivalent conductance of

NaCl

at concentration

C

and at infinite dilution are

{\lambda _C}

and

{\lambda _\infty }

, respectively. The correct relationship between

{\lambda _C}

and

{\lambda _\infty }

is given as (where, the constant

B

is positive)

View answer and explanation

Correct option: C

{\lambda _C} = {\lambda _\infty } - (B)\sqrt C

Option C is correct because the Debye-Hückel-Onsager equation describes the relationship between molar conductivity at a given concentration and at infinite dilution, and it includes a term with the square root of the concentration.
