(SO42-) sulphate. The SO42- ion, formed by reaction of sulfuric acid with a base. A compound containing the SO42- ion.

a salt or ester of sulphuric acid

Sulfate is a salt of sulfuric acid. Natural sulfates, such as sodium sulfate, calcium sulfate, and potassium sulfate, are plentiful in the body.

The drinking water limit is 250 mg/L. Sulfate (SO4-2) is widely distributed in natural waters, but is typically less than a few mg/L. In Northeastern Pennsylvania, the primary sources of sulfate in surface waters and groundwater include: acid mine drainage, acid deposition, and mineral oxidation. Standard set because of taste and aesthetic problems and sulfates laxative effects. Sulfuric salts in water form what is known as non-carbonate hardness.

A salt mineral whose anion is the sulfate radical.

One of several minerals containing positive sulfur ions bonded to negative oxygen ions.

An ion that imparts a sharp "dry" edge to beers.

(4) a mineral, compound or ion containing the radical SO4(2-).

An inorganic ion that is widely distributed in nature. It may be present in natural waters in concentrations ranging from a few to several thousand milligrams per liter.

The most common form of sulfur in natural waters. The amounts relate primarily to soil minerals in the watershed. Sulfate (SO4) can be reduced to sulfide (S--) and hydrogen sulfide (H2S) under low or zero oxygen conditions. Hydrogen sulfide smells like rotten eggs and harms fish. Sulfate (SO4--) input from acid rain is a major indicator of sulfur dioxide (SO2) air pollution. Sulfate concentration is used as a chemical fingerprint to distinguish acid lakes acidified by acid rain from those acidified by organic acids from bogs.

salt containing sulfur dioxide.

In inorganic chemistry, a sulfate (IUPAC-recommended spelling; also sulphate in British English) is a salt of sulfuric acid.
