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 everyday life, sulfates can be found in products like shampoos and detergents, where they help create lather and remove dirt. However, high levels of sulfates in water can lead to environmental issues, such as water pollution, affecting aquatic life and ecosystems.
