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
$\underset{\text { (Unstable) }}{2 FeI _{3}} \longrightarrow \underset{\text { (Stable) }}{2 FeI _{2}}+ I _{2}$
$\underset{\text { (Unstable) }}{2 FeI _{3}} \longrightarrow \underset{\text { (Stable) }}{2 FeI _{2}}+ I _{2}$
Due to strong reducing nature of $I^{-}$
$2 Fe ^{3+}+2 I ^{-} \longrightarrow 2 Fe ^{2+}+ I _{2}$
