What is the name of NH4 2S?

Ammonium sulfide ((NH4)2S) exhibits high reactivity as a sulfide reagent in anion exchange reactions that transform CoO to cobalt sulfide nanoparticles (NPs).


What is the formula of sulphide?

Sulfide is an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions.


What is NH4+ and S2?

The compound (NH4)2S ( N H 4 ) 2 S is formed from the cation ammonium (NH+4 N H 4 + ) and the sulfide anion (S2− ). As a result, the name of this compound is ammonium sulfide.


Which is correct sulfide or sulphide?

What is ammonium?

The major use of ammonia is as a fertilizer. In the United States, it is usually applied directly to the soil from tanks containing the liquefied gas. The ammonia can also be in the form of ammonium salts, such as ammonium nitrate, NH4NO3, ammonium sulfate, (NH4)2SO4, and various ammonium phosphates.


How is ammonium made?

Ammonium ions, NH4+, are formed by the transfer of a hydrogen ion from the hydrogen chloride to the lone pair of electrons on the ammonia molecule. The hydrogen’s electron is left behind on the chlorine to form a negative chloride ion.
