MCQ
Bleching powder is a mixed calcium salt of
  • $HCl$ and $HClO$
  • B
    $HClO_2$ and $HCl$
  • C
    $HClO$ and $HClO_2$
  • D
    $HCl$ and $HClO_3$

Answer

Correct option: A.
$HCl$ and $HClO$
a
$\underset{\text { (Unstable) }}{2 FeI _{3}} \longrightarrow \underset{\text { (Stable) }}{2 FeI _{2}}+ I _{2}$

Due to strong reducing nature of $I^{-}$

$2 Fe ^{3+}+2 I ^{-} \longrightarrow 2 Fe ^{2+}+ I _{2}$
