The equivalent conductance at infinite d...

The equivalent conductance at infinite dilution of NaCl, HCl and `CH_3 COONa` at 298K are 126.0, 426.0 and 91.0 `ohm^(-1)cm^(2)` respectively. The value of equivalent conductance of acetic acid at infinite dilution at the same temperature is

A

`644.0`

B

`300.0`

C

`517.0`

D

`391.0`

Text Solution

Verified by Experts

The correct Answer is:
D
The `^^_(NaCl)^(oo) = 126 , ^^_(HCl)^(oo) = 426 , ^^ _(CH_3COONa)^(oo) = 91.0`
` ^^_(CH_3OOH)^(oo) = ^^_(HCl)^(oo) + ^^_(CH_3COONa)^(oo) , ^^_(NaCl)^(oo) = 426 + 91 - 126 = 391`
