Sulfide Chemical

CAS No      12135-76-1

Application / Uses Preparation
Ammonium sulfide, is an unstable salt with the formula (NH4)2S. Aqueous solutions purporting to contain this salt are commercially available. With a pKa exceeding 15,[2] the hydrosulfide ion cannot be deprotonated to an appreciable amount by ammonia. Thus, such solutions mainly consist of a mixture of ammonia and (NH4)SH.

CAS No      1312-73-8

Application / Uses Preparation
Potassium sulfide is the inorganic compound with the formula K2S. The colourless solid is rarely encountered, because it reacts readily and irreversibly with water, a reaction that affords potassium bisulfide (KSH) and potassium hydroxide (KOH).

CAS No      1313-82-2

Application / Uses Preparation
Sodium sulfide is the name used to refer to the chemical compound Na2S, but more commonly it refers to the hydrate Na2S·9H2O. Both are colorless water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, which smells much like rotten eggs or flatus.

CAS No      1314-98-3

Application / Uses Preparation
Zinc sulfide is a chemical compound with the formula ZnS. Zinc sulfide is a white to yellow-colored powder or crystal. It is typically encountered in the more stable cubic form, known also as zinc blende or sphalerite.[1] The hexagonal form is also known both as a synthetic material and as the mineral wurtzite.[
