Chemical properties

The sulfate ion is a polyatomic anion with the empirical formula SO₄²⁻ and a molecular mass of 96.06 daltons; it consists of one central sulfur atom surrounded by four identical oxygen atoms in a tetrahedral arrangement. The sulfate ion carries a negative two formal charge and is the conjugate base of the hydrogensulfate ion, HSO₄⁻, which is the conjugate base of H₂SO₄, sulfuric acid. A polyatomic ion is an ion consisting of a molecule with covalently bonded atoms or of a metal complex that can be considered as acting as a single unit in the context of acid/base chemistry or in the formation of salts. ... An anion is an ion with negative charge. ...

A tetrahedron (plural: tetrahedra) is a polyhedron composed of four triangular faces, three of which meet at each vertex. ... In chemistry, a formal charge (FC) on an atom in a molecule is defined as: FC = number of valence electrons of the atom - number of Lone pair electrons on this atom - half the total number of electrons participating in covalent bonds with this atom. ... Within the Brønsted-Lowry (protonic) theory of acids and bases, a conjugate acid is the acid member, HX, of a pair of two compounds that transform into each other by gain or loss of a proton. ...

A sulfate salt forms when a positively charged ion attaches to the negatively charged oxygen atoms of the ion, forming an ionic compound. Almost all sulfates are soluble in water at standard temperature and pressure. Exceptions include calcium, strontium and barium sulfates. A chemical compound is a chemical substance formed from two or more elements, with a fixed ratio determining the composition. ... A substance is soluble in a fluid if it dissolves in that fluid. ...

Uses

Sulfates, also known as sulfur oxides, are important in both the chemical industry and biological systems:

• The Lead-acid battery typically uses sulfuric acid.
• Organisms living near deep sea thermal vents depend on sulfates for energy in lieu of the sun.
• Copper sulfate is a common algaecide.
• Magnesium sulfate, commonly known as Epsom salts, is used in therapeutic baths.

Sulfates occur as microscopic particles (aerosols) resulting from fossil fuel and biomass combustion. They increase the acidity of the atmosphere and form acid rain. There is a negative radiative forcing from aerosols because, while in the atmosphere, they reflect incoming solar radiation. This is an increase in albedo.
