Textbook Question
Chapter 8, Problem 62AP
When exposed to air containing hydrogen sulfide, lead-based paints turn black because the Pb2+ ions react with the H2S to form black lead sulfide (PbS). This has caused the darkening of old oil-based paintings. Hydrogen peroxide lightens the paints by oxidizing the black sulfide (S2-) to white sulfates (SO42-).
(a) Write the equation for the darkening reaction.
(b)Write the equation for this reaction that lightens the paints.
