The paper strip test for hydrogen sulfide production is impregnated with which chemical?

Explanation:
Hydrogen sulfide detection on a paper strip relies on a chemical that captures the gas and makes it visible. Lead acetate on the strip reacts with any H2S produced by the organism, forming lead sulfide, a dark precipitate that signals a positive result. This gives a quick, clear readout of H2S production. The other substances listed have roles in different media or tests and do not trap and reveal H2S in this strip format.
