1.	B +NaOH rarrDirty green ppt. overset(NH_(3))underset(("excess"))rarr Insoluble Find the option where blut ppt is obtained.
Answer» When A is treated with `K_(4)[FE(CN)_(6)]` When B is treated with `K_(4)[Fe(CN)_(6)]` When A is treated with `K_(3)[Fe(CN)_(6)]` When B is treated with `K_(3)[Fe(CN)_(6)]` Solution :`X rarr Fe_(2)O_(3), A rarr FeCI_(3), B rarr FeI_(2)`, `FeI_(2)+2NaOH rarr underset(("Dirty green ppt"))(Fe(OH)_(2)darr+2NaI)` `Fe^(3+) +[Fe(CN)_(6)]^(4-)` gives same blue colouration as `Fe^(2+) +[Fe(CN)_(6)]6(3-)`
