The molar conductances of NaCI, HCI and ...

The molar conductances of `NaCI, HCI` and `CH_3 COONa` at infinite dilution are `12.45, 426. 16` and ` 91 "ohm"^(-1) cm^2 "hol"^(-1)` respectively. The molar conductance of `CH_3COOH` at infinite dilution is .

A

201.28 `ohm^(-1)cm^(2)`

B

`390.71 ohm cm^(2)`

C

`698.28ohm cm^(2)`

D

`540.48ohm cm^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`^^_(C_(2)H_(5)COOH)^(0)=^^_(C_(2)H_(5)COONa)^(0)+^^_(HCl)^(0)-^^_(NaCl)^(0)`
`=91+426.16-126.45`
`=390.71ohm^(-1)cm^(2)`.
