The molar ionic conductance at infinite ...

The molar ionic conductance at infinite dilution of `K^(+)` and `SO_(4)^(2-)` are 73.5 and 160 `Scm^(2)mol^(-1)` respectively.The molar conductance of solution of `K_(2)SO_(4)` at infinite dilution will be

A

233.5

B

307

C

153.5

D

467

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(2)SO_(4)to2K^(+)+SO_(4)^(2-)`
`(lamda_(m)^(@))_(K_(2)SO_(4))=2(lamda_(m)^(@))_(K)+(lamda_(m)^(@))_(SO_(4)^(2-))`
`=2xx73.5+160+160`
