Fe^(+3) ions in an aqueous solution gives deep red colouration with both sodium acetate (in excess) and ammonium thiocyanate(slightly acidic). The deep red colouration obtained with ammonium thiocyanate gets decolourised on addition of a solution containing F^(-) ions. Which one of the following statements is false with respect to deep red colouration produced with NH_(4)SCN?

1.	Fe^(+3) ions in an aqueous solution gives deep red colouration with both sodium acetate (in excess) and ammonium thiocyanate(slightly acidic). The deep red colouration obtained with ammonium thiocyanate gets decolourised on addition of a solution containing F^(-) ions. Which one of the following statements is false with respect to deep red colouration produced with NH_(4)SCN?
Answer» The DEEP red colour is bleached by `Hg(II)` ions. The deep red colouration is due to the formation of a non-dissociated iron (III) thiocyanate complex The deep red coloured compound can be extracted by either or amyl alcohol None of the above Solution :`Fe(SCN)_(3) OVERSET(F^(-))RARR [feF_(6)]^(3-)` colourless `(sp^(3)d^(2))` `underset(("Red colouration"))([Fe_(3)(OH)_(2)(CH_(3)COO)_(6)]^(+))+4H_(2)O rarr underset(("Red ppt"))(3Fe(OH)_(2)CH_(3)COOdarr)+3CH_(3)COOH +H^(+)`
