The values of wedge(eq)^(oo) for NH(4)Cl...

The values of `wedge_(eq)^(oo)` for `NH_(4)Cl,NaOH` and `NaCl` are, respectively, `149.74,248.1`, and `126.4 ohm^(-1)cm^(2)eq^(-1)`. The value of `wedge_(eq)^(oo)NH_(4)OH` is

A

`371.44`

B

`271.44`

C

`71.44`

D

It cannot be calculated from the data given.

Text Solution

Verified by Experts

The correct Answer is:
B
`^^_(eq)^(oo)(NH_(4)OH)`
`=^^_(eq)^(oo)(NH_(4)Cl)+^^_(eq)^(oo)(NaOH)-^^_(eq)^(oo)(NaCl)`
`=(149.7+248.1-126.4)`
`= 271.44 Omegacm^(2)eq^(-1)`
