A solution contians `0.1 M NaCl, 0.01 M NaBr` and `0.001 M Nal`.solid `AgNO_(3)`is gradually added to the solution and its addition
`K_(sp)AgCl = 10^(-10), K_(sp) AgBr = 10^(-13)`,
`K_(sp)AgI = 10^(-17)`
choose the correct statements

Options

A. `AgI` precipitates first
B. The maximum `[I^(-)]` which can be maintained in the solution so that only `AgI` is precipitate is `10^(-6) M`.
C. When the precipitation of `AgCl` just starts, `[I^(-)]` in the solution is `10^(-8) M`
D. If sufficient NaI is added to a saturated solutions of `AgCl`, precipitate of `Agl` is obtained.

Answer

A, B, C, D

Explanation

`{:(10ml(N)/(20)NaOH +,20ml(N)/(20)HCl),("milli eq."=10 xx 1/20 = 1/2,"milli eq." = 20 xx 1/20 = 1):}`
Solution also turn s methly orange red
`[H^(+)] gt [H^(-)]`
then (B) (C) and (D) are correct.
