The specific conductance of a saturated ...

The specific conductance of a saturated solution of silver bromide is `kScm^(-1)` . The limiting ionic conductivity of `Ag^(+)` and Brions are x and y, respectively. The solubility of silver bromide in g `L^(-1)`
is: (molar mass of AgBr=188)

A

`(kxx1000)/(x-y)`

B

`(k)/(x+y)xx188`

C

`(kxx1000xx188)/(x+y)`

D

`(x+y)/(k)xx(1000)/(188)`

Text Solution

Verified by Experts

The correct Answer is:
C
`wedge_(m)=(k)/(M)xx1000(x+y)=(k)/(M)xx1000 rarr M=(1000 xxk)/(x+y),` solubility =`(kxx1000xx188)/(x+y)`
