PbS + 4O3 → PbSO4 + 4O. Lead(II) sulfide react with ozone to produce lead(II) sulfate and oxygen. The reaction proceeds at room temperature.

What happens when o3 reacts with PbS?

(i) Ozone oxidizes lead sulfide to lead sulphate. Lead sulfide has black color whereas lead sulphate has white color. The byproduct of the reaction is dioxygen. ... Potassium hydroxide and oxygen are the other byproducts of this reaction.

What happens when hydrogen peroxide is treated with lead sulphide?

Lead sulfide (PbS) reacts with hydrogen peroxide ( H₂O₂) and produce lead sulfate (PbSO₄) and water as products. This reaction is a redox reaction. ... PbS is a black precipitate and PbSO₄ is a white precipitate.
