In 1L saturated solution of `AgCI[K_(SP)(AgCI)= 1.6xx10^(-10)], 0.1` mole of CuCI `[K_(SP)(CuCI)=1.0xx10^(-6)]` is added. The resulrant concentration of `Ag^(+)` in the solution is `1.6xx10^(-x)`. The value of `"x"` is:

Answer

7

Explanation

`:'K_(sp)(CuCl)gt gt K_(sp)(AgCl)`
Thus assume `[Cl^(-)]` in solution comes from `CuCl` only.
`[Cl^(-)]=sqrt(K_(sp)CuCl)=10^(-3)M`
For `AgCl[Ag^(+)][Cl^(-)]=1.6xx10^(-10)`
`[Ag^(+)]=1.6xx10^(-7)`
`x=7`
