Acid potassium sulfate (K2SO4) is a white, fine crystalline powder with a slight sulfur odor that is commonly used as a fertilizer in agriculture. It is also known as dipotassium sulfate, sulfate of potash, or double sulfate of potash.

Acid potassium sulfate is an acidic form of potassium sulfate, which has a pH of around 5.5. Its chemical formula is K2SO4, which is a salt of sulfuric acid and one molecule of potassium. It is highly soluble in water, and when dissolved in water forms a very acidic solution.

Acid potassium sulfate is a popular fertilizer for many plants, including tomatoes, potatoes, fruits, and vegetables. It helps to improve soil fertility, increase the water-holding capacity of soil, reduce soil erosion, and increase crop yields. It is also used as a source of potassium in animal feed, as it is one of the essential elements needed by animals.

For use as a fertilizer, acid potassium sulfate is applied in either granular or liquid form. The granules can be mixed with other fertilizer materials and incorporated into the soil, while the liquid form can be mixed into irrigation water.

Acid potassium sulfate can also be used to prevent and treat certain plant diseases, including powdery mildew and leaf spot. When applied as a foliar spray, it will form a protective coating on the leaves, preventing certain pathogens from entering the plant.

In addition to its agricultural uses, acid potassium sulfate is also used in some industrial processes, such as the manufacture of paint and other chemicals. It can also be used in food processing, as a preservative and a stabilizer, as well as in the production of yeast and in the tanning of leather.
