`K_(sp) (25^(@)C)` of `Ag_(2)CrO_(4)` is `4 xx 10^(-12)`. Which of the following mixer will bring about precipitatin of `Ag_(2)CrO_(4)`.
A. `10 mL 3 xx 10^(-4) M AgNO_(3) + 10 mL 10^(-4) M Na_(2)CrO_(4)`
B. Adding `10` milli moles of `Na_(2)CrO_(4)` to `100` mL ofsaturated `AgCl(K_(sp) = 2 xx 10^(-10))` solution
C. Mixing equal volumes of `10^(-4) M AgNO_(3)` with `10^(-4) M Na_(2)CrO_(4)` solution
D. `10 mL 10^(-3) M AgNO_(3) + 15 mL 10^(-3) M Na_(2)CrO_(4)`

Best answer
Correct Answer - B::D
`K_(sp) Ag_(2)CrO_(2) = 4 xx 10^(-12)`
In B & D option
`[Ag^(+)]^(2) [CrO_(4)^(2-)] gt K_(sp)`
`:.` Precipitation occurs in case of `B` & D
