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

Answer»

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

Solution :`{:(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.
