Sulphur is a bright yellow, non-metallic element found in nature, often in volcanic regions and mineral deposits. It is essential for life and is a key component of amino acids, which are the building blocks of proteins. Sulphur is commonly used in fertilizers, helping to improve soil health and crop yields. In addition to agriculture, sulphur is used in the production of sulfuric acid, a vital industrial chemical. It also plays a role in the manufacture of rubber, detergents, and pharmaceuticals. Its distinct smell, often compared to rotten eggs, comes from hydrogen sulfide, a compound containing sulphur.
