    Sulfuric acid | H2SO4 - PubChem

    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 equivalent oxygen atoms in a tetrahedral arrangement. The sulfate ion carries a negative two charge and is the conjugate base of the hydrogen sulfate ion, HSO4-, which is the conjugate base of H2SO4, sulfuric acid.
