At `18^(@)C` the mobilities of `NH_(4)^(+)` and `CIO_(4)^(-)` ions are `6.6 xx 10^(-4)` and `5.7 xx 10^(-4)cm^(2)"volt"^(-1)sec^(-1)` at infinite dilution. Calculate equivalent conductance of ammonium chlorate solution.

Text Solution

Verified by Experts

`Lambda_(NH_(4)ClO_(4))^(@)=lambda_(NH_(4)^(+))^(oo)+lambda_(ClO_(4)^(-))^(oo)`
`=(U_(NH_(4)^(+))^(oo)+U_(ClO_(4)^(-))^(oo))F`
`=(6.6xx10^(-4)+5.7xx10^(-4))xx96500`
`=118.69 ohm^(-1) cm^(2) eq^(-1)`
