The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO2− 4. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid.
Sulfate is carried to bodies of water by rain and through solution of sulfate compounds in sedimentary geologic formations within the drainage basin. The most frequently encountered forms of sulfur in fresh waters are as the anion sulfate (SO4-2) in combination with the common cations and as hydrogen sulfide (H2S).
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.
Sulphate (SO 4 2-) is one of the most widely available chemical compounds accessible as naturally occurring minerals on earth. It is mostly found in the environment as a result of atmospheric and terrestrial processes.
Anhydrous, it is a white crystalline solid of formula Na 2 SO 4; the decahydrate Na 2 SO 4 ·10H 2 O has been known as Glauber's salt or, historically, sal mirabilis since the 17th century. Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping.
The sulfate ion carries a negative two charge and is the conjugate base of the bisulfate (or hydrogen sulfate) ion, HSO 4−, which is the conjugate base of H 2 SO 4, sulfuric acid. Organic sulfates, such as dimethyl sulfate, are covalent compounds and esters of sulfuric acid.
sulfate, any of numerous chemical compounds related to sulfuric acid, H 2 SO 4. One group of these derivatives is composed of salts containing the sulfate ion, SO 42-, and positively charged ions such as those of sodium, magnesium, or ammonium; a second group is composed of esters, in which the hydrogen atoms of sulfuric acid have been replaced ...
