Sulfate is a chemical compound that contains sulfur and oxygen, typically represented by the formula SO₄²⁻. It is commonly found in nature, often in minerals and salts, and plays a significant role in various biological and environmental processes. Sulfates are important for plant growth and are often used in fertilizers to enhance soil quality. In addition to its natural occurrences, sulfate is also found in many everyday products, such as detergents and shampoos, where it helps to create lather and improve cleaning efficiency. However, excessive sulfate levels in water can lead to environmental issues, affecting aquatic life and water quality.
