sulfates, plural; sulphates, plural;
  1. A salt or ester of sulfuric acid, containing the anion SO42 or the divalent group OSO2O

  1. a salt or ester of sulphuric acid
  2. convert into a sulfate
  3. In inorganic chemistry, a sulfate (IUPAC-recommended spelling; also sulphate in British English) is a salt of sulfuric acid.
  4. Biochemical sulfation is a phase II enzyme reaction. This biotransformation process uses its cosubstrate 3'-phosphoadenosine-5'-phosphosulfate (PAPS) to transfer sulfonate to a xenobiotic. ...
  5. (Sulfation (Battery)) Lead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery. ...
  6. (Sulfates) Sulfuric salts in water. They form what is known as non-carbonate hardness.
  7. (Sulfates) Sulphur salts, abundant in soil and natural water, and in industrial, domestic or municipal waste. Theses chemical compounds can considerably damage concrete durability.
  8. (Sulfates) The groups of aerosols that originate as sulfur dioxide gas and are converted to aerosols in the atmosphere.
  9. (Sulfates) The second most important class of cave minerals, after the carbonates, is the sulfates. The third most common cave mineral, gypsum (CaSO4·2H2O), is in this class, as are two other fairly common minerals, epsomite (MgSO4·7H2O) and mirabilite (NaSO4·10H2O). ...
  10. (sulfates) a group of minerals (e.g. gypsum and barite) in which the sulfate radical (SO4) is an important constituent
  11. (Sulfation (Battery)) The formation of lead sulfate of such physical properties that it is extremely difficult, if not impossible, to reconvert it to active material.
  12. (Sulfation) A condition that afflicts unused and discharged batteries; large crystals of lead sulfate grow on the plate, instead of the usual tiny crystals, making the battery extremely difficult to recharge.
  13. (Sulfation) Even though Lead Sulfate is created in the materials of plates during normal discharging, this term is used to describe the generation of a different form of Lead Sulfate which will not readily convert back to normal material when the battery is charged. ...
  14. (Sulfation) A condition in a battery that reduces its output. The sulfate in the battery that is not converted tends to harden on the plates, resulting in permanent damage to the battery.
  15. (Sulfation) The process of a sulfur-containing compound being paired with toxins, residuals of prescription drugs, food additives, bacteria and chemicals from the environment. These compounds are then removed from the body.
  16. (sulfation) The formation of sulfuric acid esters from alcohols or olefins (synthetic fibers, such as polypropylene).
  17. Sulfate is a natural forming mineral found in water. Sulfate effects the taste of water, and when combined with bacteria or heated (water heater) may effect the odor. High levels of Sulfate may impact the digestion system causing a laxative effect. ...
  18. An ion that imparts a sharp "dry" edge to beers.
  19. A chemical compound that can cause laxative effects and give off a medicinal taste in concentrations around 30 gpg. In high concentration with high calcium hardness, it forms a white insoluble compound that is difficult to remove.
  20. A compound in which the hydrogen of sulfuric acid is replaced by either metal or by an organic radical, to become a sulfate salt or sulfate ester respectively.
  21. One of several minerals containing positive sulfur ions bonded to negative oxygen ions.
  22. 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. ...
  23. Sources of sulfate (SO4^2-) in groundwater include the dissolution of gypsum and anhydrite, the weathering of pyrite and iron sulfides, residual formation water, the lateral intrusion of seawater, precipitation that contains sulfur oxides, and marine aerosols. ...
  24. Naturally occurring but can indicate outside contamination of the water supply. Causes gastrointestinal discomfort in individuals who are not accustomed to drinking the water.
  25. Artificial liquid. Made with sulfated oils. Used to make manufactured soaps and detergents. Harmful to marine life and the environment.
