The equivalent conductance of NaCl at co...

The equivalent conductance of NaCl at concentration C and at infinite dilution are `lambda_(C)` and `lambda_(oo)`, respectively. The correct relationship between `lambda_(C)` and `lambda_(oo)` is given as (where, the constant B is positive)

A

`lambda_(c) = lambda_(oo) + (B) sqrtC`

B

`lambda_(c) = lambda_(oo) + (B) C`

C

`lambda_(c) = lambda_(oo) - (B) C`

D

`lambda_(c) = lambda_(oo) - (B) sqrtC`

Text Solution

Verified by Experts

The correct Answer is:
D
According to Debye Huckel Onsager equation ,
`Lambda_(c) = Lambda_(oo) - A sqrtC`
Here `A = B `
`Lambda_(c) = Lambda_(oo) - BsqrtC`
