Sulfate salts are chemical compounds that contain the sulfate ion, SO4^2-. They are formed when sulfuric acid reacts with various metals or bases. Common examples include sodium sulfate and calcium sulfate, which are often used in industries such as detergents and construction. These salts are typically soluble in water, allowing them to dissociate into their constituent ions. Sulfate salts play important roles in various applications, including agriculture as fertilizers and in the production of gypsum for drywall. Their properties can vary widely depending on the metal or element they are combined with.
