The reagents used in the test for sulfide are ammonium peroxydisulfate and hydrogen peroxide. These reagents act as oxidizing agents and produce sulfur when they react with sulfide ions.
The reagents commonly used in the test for sulfide are ammonium peroxydisulfate ((NH4)2S2O8) and hydrogen peroxide (H2O2). These reagents act as oxidizing agents and can be used to detect the presence of sulfide ions in a solution. For example, when sulfide ions react with hydrogen peroxide, they produce sulfur and water:
S2- + H2O2 → S + 2OH-
Similarly, ammonium peroxydisulfate can be used to test for sulfide by reacting with sulfide ions to form sulfur and other products.
