If K(sp) of Ag(2)CO(3) is 8 xx 10^(-12),...

If `K_(sp)` of `Ag_(2)CO_(3)` is `8 xx 10^(-12)`, the molar solubility of `Ag_(2)CO_(3)` in 0.1 M `AgNO_(3)` is `x xx 10^(-10) M`. The numerical value of x is ________.

A

`8xx10^(-10) M`

B

`8xx10^(-12) M`

C

`8xx10^(-13) M`

D

`8xx10^(-11) M`

Text Solution

Verified by Experts

The correct Answer is:
A
`Ag_(2)CO_(3) to underset(2s+0.1)(2Ag^(+)) + underset(s)(CO_(3)^(-))`
`(2s+0.1)^(2)(s)=8xx10^(-12)`
`2s ltlt0.1`
`10^(-2)xxs=8xx10^(-12)`
`s=8xx10^(-10) mol e//L`
