Calculate `Lambda_(HO Ac)^(oo)` using appropriate molar conductances of the electrolytes listed above at infinite dilution in `H_(2) O` at `25^(@) C`

A

`217.5`

B

`390.7`

C

`552.7`

D

`517.2`

Text Solution

Verified by Experts

The correct Answer is:
B
`Lambda_(HCl)^(oo) = 426.2 " " … (i)`
`Lambda_(AcONA)^(oo) = 91.0 " " … (ii)`
`Lambda_(NaCl) = 126.5 " " … (iii)`
`Lambda_(AcOH)^(oo) = (i) + (ii) - (iii) = [426.2 + 91.0 - 126.5] = 390.7`
