Calculate `Lambda_(HOAc)^(@)` using appropriate molar conductances of the electrolytes listed above at infinite dilution in water at `25^@C`.

A

`517.2`

B

`552.7`

C

`390.7`

D

`217.5`

Text Solution

Verified by Experts

The correct Answer is:
C
`(Lambda_(oo))_(HOAc) = [(Lambda^@)_(HCl) + (Lambda^@)_(NaOAc)] - (Lambda^@)_(NaCl)`
`(426.2 + 91) - (126.5) = 390.7`.
