is potassium sulfide soluble in water?

Potassium sulfide (K2S) is an inorganic compound that occurs naturally in salts. It is a metal halide salt that contains potassium and chlorine. It has a white or colorless appearance and a strong sulfur smell. It is a mildly corrosive salt that dissolves quickly in water.

K2S is commonly used as a fertilizer, primarily in soils that are low in potassium. It increases plant growth and reduces wilting. It aids in enzyme activation and protein synthesis, enhances photosynthesis, stimulates starch and sugar formation, and helps regulate the exchange of water, oxygen and carbon dioxide between cells and leaves.

It is also an important mineral in the body, helping maintain turgor and regulating the flow of water to cells. It is required by many cellular processes and acts as an antioxidant, helping to protect the cell against free radicals.

A common reagent in analytical chemistry; it is used in a number of pharmaceutical preparations. It is also a component of pyrotechnics, particularly in Asia to manufacture fireworks senki hanabi.

Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. They are typically soluble in water, but not as easily as fluorides or oxides. They are sometimes deposited by sputtering targets or evaporated to form thin films for uses such as solar energy materials and fuel cells. Some forms of sulfate compounds are also dissolved or coated on nanoparticles for uses in biomedical research and drug delivery systems.
