Solid `AgNO_(3)` is gradually added to a solution which is `0.01M` n `Cl^(-)` and `0.01 M` in `CO_(3)^(2-) K_(sp) AgCl=1.8xx10^(-10)` and `K_(sp)Ag_(2)CO_(3)=4xx10^(-12)`
The minimum concentration of `Ag^(+)` required to start the precipation of `Ag_(2)CO_(3)` is

A

`1.8xx10^(-9)M`

B

`1.8xx10^(-5)M`

C

`1.2xx10^(-4)M`

D

`9xx10^(-6)M`

Text Solution

Verified by Experts

The correct Answer is:
D
`[Cl^(-)]=(K_(sp)AgCl)/([Ag^(+)])=(1.8xx10^(10))/(2xx10^(-5))`
`=9xx10^(-6)M`
