What is the molar solubility of Ag(2)CO(...

What is the molar solubility of `Ag_(2)CO_(3)` `(K_(sp)=4xx10^(-13))` in 0.1 M `NaCO_(3)` solution?

A

`10^(-6)`

B

`10^(-7)`

C

`2xx10^(-6)`

D

`2xx10^(-7)`

Text Solution

Verified by Experts

The correct Answer is:
A

`Ksp=[Ag^(+1)][CO_(3)^(-2)]`
`Ag_(2)CO_(3)hArr2Ag^(+)+CO^(-2)`
`25^(1).5^(1)+0.1`
`Na_(2)CO_(3)to2Na^(+)CO_(3)^-2`
`4xx10^(-13)=(2S^(1))^(2)(S^(1)+c)`
`S^(1)=sqrt((10^(-13))/(10^(1)))=10^(-6)`
