Ammonium sulphate

Ammonium sulphate

Ammonium sulfate is an inorganic salt with the chemical formula (NH₄)₂SO₄. It typically appears as a white crystalline solid or powder and is highly soluble in water. Ammonium sulfate is widely used in agriculture as a nitrogen fertilizer, providing essential nutrients that support plant growth. It is particularly valued for its ability to lower soil pH, making it beneficial for crops that thrive in acidic conditions.

In addition to its primary use as a fertilizer, ammonium sulfate is also employed in various industrial applications. It is used in the treatment of drinking water to remove impurities and in the food industry as a food additive. In laboratories, ammonium sulfate is used for protein purification through a process called "salting out," where it helps precipitate proteins from solution.
