MCQ
A blood red colour is obtained when Ferric Chloride solution reacts with
  • A
    $KCN$
  • ✓
    $KSCN$
  • C
    $K_4[Fe(CN)_6]$
  • D
    $K_3[Fe(CN)_6]$
✓

Answer

Correct option: B.
$KSCN$
b
The reaction of ferric chloride with potassium thiocyanate $(K S C N)$ gives a blood-red solution

$F e C l_{3}+3 K S C N \rightarrow F e(S C N)_{3}+3 K C l$
