Which of the following equations depict the oxidising nature of H₂O₂?

(i) 2MnO₄^- + 6H⁺ + 5H₂O₂ → 2Mn²⁺ + 8H₂O + 5O₂

(ii) 2Fe³⁺ + 2H⁺ + H₂O₂ → 2Fe²⁺ + 2H₂O + O₂

(iii) 2I^- + 2H⁺ + H₂O₂ → I₂+ 2H₂O

(iv) KIO₄ + H₂O₂→ KIO₃ + H₂O + O₂

H₂S has minimum boiling point.

PbS + 4H₂O_2->PbSO₄ + 4H₂O.

Volume strength of H₂O₂ = Molarity * 11.2

HF molecules are associated with strong intermolecular hydrogen bonding hence its boiling point is the highest

Compound             Melting Point (K)

HF                          190

HCl
