Which one of the following reactions represents the oxidising property of H ₂ O ₂ ?
Options
- Aaligned & 2 KMnO ₄+3 H ₂ SO ₄+5 H ₂ O ₂ & K ₂ SO ₄+2 MnSO ₄+8 H ₂ O +5 O ₂ aligned
- Baligned & 2 ~K ₃ [ Fe ( CN )₆ ]+2 KOH + H ₂ O ₂ & 2 ~K ₄ [ Fe ( CN )₆ ]+2 H ₂ O + O ₂ aligned
- CPbO ₂+ H ₂ O ₂ PbO + H ₂ O + O ₂
- D2 KI + H ₂ SO ₄+ H ₂ O ₂ K ₂ SO ₄ + I ₂+2 H ₂ O
Correct answer
D. 2 KI + H ₂ SO ₄+ H ₂ O ₂ K ₂ SO ₄ + I ₂+2 H ₂ O
Step-by-step solution
The reaction in which H ₂ O ₂ is reduced while the other reactant is oxidised, represents the oxidising property of H ₂ O ₂ . aligned & (oxidising & agent) & oxidation & aligned
