Description and Uses
Ammonium sulfide solution is used occasionally in photographic developing, to apply patina to bronze, and in textile manufacturing. Ammonium sulfide is a very useful reagent in mineral analysis. Used in continuous culture of saccharomyces cerevisiae, useful in a double staining technique for visualization of astrocytes and microglia from brain sections and astroglial cell cultures. It plays an important role to modify the surface of low κ dielectric thin films. It is essential for molecular beam epitaxy regrowth. It is an unstable salt and acts as a selective reducing agent.
