PbS (S: -2 to +6 in PbSO₄) loses electrons, reducing H₂O₂ (O: -1 to -2).
Ref: NCERT Class 11 Chemistry > Chapter 7: Redox Reactions > Topic: Oxidizing and Reducing Agents and Strength
O (-1 in H₂O₂) becomes -2 in H₂O, gaining electrons.
Ref: NCERT Class 11 Chemistry > Chapter 7: Redox Reactions > Topic: Electrode Potential and Electrochemical Series and Galvanic Cells
H₂O₂ (O: -1) is reduced to -2 in H₂O and oxidized to 0 in O₂; it acts as both, but here it oxidizes itself.
