Question

Which one of the following statement is false with respect to deep red colouration produced with $N{H}_{4}SCN?$

• A. The deep red colour is bleached by $Hg\left(II\right)$ ion
• B. The deep red colouration is due to the formation of a non-dissociated iron $\left(III\right)$ thiocyanate complex.
• C. The deep red coloured compound can be extracted by ether or amyl alcohol
• D. None of the above

Answer 1

The correct option is D None of the above

With ferric ions, thiocyanate ions give a blood red coloration of $Fe(SCN{)}_3$.
The deep red colour is bleached by $Hg\left(II\right)$ ion.
And deep red coloured compound can be extracted by ether or amyl alcohol.
