Hydrogen peroxide is _________.

(i) An oxidizing agent

(ii) A reducing agent

(iii) Both an oxidizing and a reducing agent

(iv) Neither oxidizing nor reducing agent.

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
