3. A sour substance, in chemistry: A substance belonging to a class of which the commonest and most typical members are sour, and have the property of neutralizing alkalis, and of changing vegetable blues to red; all of which are compounds of hydrogen with another element or elements (oxygen being generally the third element), and in the decomposition of a compound substance are relatively electro-negative, and borne to the positive pole.
2. A popular term for the atmospheric deposition of acidified rain, snow, sleet, hail, acidifying gases and particles, as well as, acidified fog and cloud water.
3. Rain, snow, sleet or fog water having a pH less than 5.65.
4. The deposition of acidifying substances from the atmosphere during a precipitation event.
It has been used to treat diarrhea, reduce bronchial secretions, and reduce night sweats.
2. Arachidonic acid is found only in animal fats, as in egg yolk and liver.
3. Coined from the modern Latin stem arachid-, "peanut" (from Greek arakhos, "a type of leguminous plant").
2, A fatty acid derived from butter but rare in most fats.
It is a viscid liquid with a rancid odor; and is used in disinfectants, emulsifying agents, and pharmaceuticals.
It is also useful in treating excessive bleeding due to increased fibrinolytic activity in the blood.
This substance as it occurs in living organisms produces the stinging sensation that results from the bite of red ants and is also found in spiders, in pine needles, as well as in stinging nettles.
Formic acid is made commercially by the reaction of carbon monoxide with sodium hydroxide and is used in dyeing and finishing textiles, treating leather, and producing fumigants, insecticides, and refrigerants.
Going back to the Latin word for "ant", it was first obtained in 1670 from the distillation of ants.
Commercial molybdic acid is a solution of ammonium molybdate or molybdenum trioxide.
Major sources are vegetable and seed oils.
Ingestion of a diet rich in oxalates or a genetic disorder of glycine metabolism (primary hyperoxaluria) may lead to the formation of oxalate calculi in the urinary tract.
2. Any of a group of drugs that inhibit the activity of proton pumps and are used to restrain gastric acid secretion in the treatment of ulcers and gastroesophageal reflux disease.
3. Any of a group of drugs used to treat excessive secretion of acid in the stomach and any resulting ulcers.
They block the enzyme (proton pump) in the cells of the gastric glands that secrete hydrochloric acid.
2. An uncomfortable burning sensation in the lower chest, usually caused by stomach acid flowing back into the lower end of the esophagus.
3. A burning sensation, usually centered in the middle of the chest near the sternum, caused by the reflux of acidic stomach fluids that enter the lower end of the esophagus.
2. An optically inactive form of tartaric acid which can be separated into dextrorotatory and levorotatory components and is sometimes found in grape juice during the making of wine.
2. An isomeric form of lactic acid produced by muscle tissue during the anaerobic metabolism of glucose.
2. Any of a group of reducing amido acids that are essentially carbohydrates and are found especially as components of blood glycoproteins and mucoproteins
The ferrous sulfate can further react to form ferric hydroxide, or "yellowboy", a yellow-orange iron precipitate found in streams and rivers polluted by acid mine drainage.
It can be wet precipitation (rain, snow, or fog) or dry precipitation (absorbed gaseous and particulate matter, aerosol particles or dust).
Acid rain has a pH below 5.6. Normal rain has a pH of about 5.6, which is slightly acidic. The term pH is a measure of acidity or alkalinity and ranges from 0 to 14.
A pH measurement of 7 is regarded as neutral. Measurements below 7 indicate increased acidity, while those above indicate increased alkalinity.
