sulfataattien

Sulfataatit are the anions SO4^2-, which are derived from sulfuric acid. They are a very common and important class of chemical compounds. In aqueous solutions, sulfate ions are generally soluble, with the notable exceptions of barium sulfate (BaSO4), strontium sulfate (SrSO4), and lead(II) sulfate (PbSO4). These insoluble sulfates are often encountered as precipitates in chemical reactions.

Sulfates play a crucial role in various natural and industrial processes. For instance, they are found in many minerals, such as gypsum (CaSO4·2H2O) and anhydrite (CaSO4), which are used in construction. In the environment, sulfates are part of the sulfur cycle and can be transported through the atmosphere and water systems. Excessive sulfate levels in water can lead to issues like corrosion and affect taste. Industrially, sulfates are used in the production of sulfuric acid, fertilizers, detergents, and in electroplating. Their chemical properties, such as their stability and ability to form salts, make them versatile building blocks in chemistry.
