Question

What are the reagents needed to prepare H2S in the laboratory? 

Answer

In the laboratory, H2S can be prepared by reacting a metal sulfide with an acid. The reagents needed are:

  1. Metal sulfide: The most commonly used metal sulfide is ferrous sulfide (FeS), although other metal sulfides such as zinc sulfide (ZnS) or copper sulfide (CuS) can also be used.
  2. Acid: Hydrochloric acid (HCl) or dilute sulfuric acid (H2SO4) can be used to react with the metal sulfide.
