Does anyone know what humic acid or fulvic acid is?
85568
sup. humic n fulvic acids are to do with plants. they can be extracted from plants and the earth. Humic acids promote microbacterial growth. these acids are natural chelate as opposed to synthetic chelates like ethylenediaminetetraacetic acid (EDTA).

Muriatic acid is just the old name for Hydrochloric acid.\n\nGood point about diluting Sciguy.  But pour the acid into the water, not the water into the acid, to prevent boiling.

Ascorbic acid is Vit C.  Acidic acid is Vinegar.

Humus is typically dark brown to black in color. More likely, the brown comes from organic materials or iron and iron oxides.

Vinegar is a weak acid (Acetic Acid, HC2H3O2).\nAmmonia [and/or Ammonium Hydroxide] is a weak base (NH3 + H2O --> NH4OH).\n\nBy "weak", I am not refering to the reactivity of the substances, but rather the amount the substances will dissassociate into ions in solution.  A weak acid/base will not dissassociate completely into ions in solution as would a "Strong" acid/base would.\n\nWhen you react an acid and base together, you get a neutralization reaction which produces water and a salt.\nIn the case of Ammonia and vinegar, the salt you would producce is Ammonium Acetate (NH4C2H3O2).

Citric acid would probably be the easiest to come by.\nAsorbic acid (Vitamin C) is also anothe weak organic acid.

those two are proteins and nucleic acids (DNA and RNA).  those two are present in all the living beings (the only problem with them is, that in viruses they are present - but some scientists belive that viruses are not living materia).\n\nthere are other organic components in living materia, such as lipids, carbohzdrates, vitamins, ferments etc.\n\nand those organic moleculas are composed of minerals - those which are listed in the first answer.

Sulfuric Acid removes water from carbohydrates and other organic substance. It plays an important role as a dehydrating agent and in the manufacturing of a wide range of products, including pigments, textile fibers, explosives, petroleum, alcohols, and detergents.  It serves as an electrolyte in lead storage batteries and as a pickling agent during the processing of steel. The main use of sulfuric acid is in the fertilizer industry which accounts for approximately 59% of its total consumption.

Acetic acid is a fancy name for vinegar...if you mix it with baking soda it fizzes, that's evidence of acidity... also you can mix it with hydrogen peroxide. I can't think of an easy third test...maybe ammonium nitrate... all these tests would involve litmus paper by the way.

Acetic acid (HC2H3O2, or CH3COOH). Vinegar.

Any acid.  Vinegar is the best probably.

Acetic acid is ethanoic acid, not methanoic.  It is methane carboxylic acid, CH3COOH.  You account both carbons in the name.\n\nhttp://www.jtbaker.com/msds/englishhtml/a0326.htm

Uric acid (or uricite) is an organic compound of carbon, nitrogen, oxygen and hydrogen with the formula C5H4N4O3.\n\n In humans and higher primates, uric acid is the final oxidation product of purine metabolism. In most other mammals, the enzyme uricase further oxidizes uric acid to allantoin.\nUric acid is also the end product of nitrogen metabolism in birds and reptiles. In such species, it is excreted in feces as a dry mass. \nHumans produce only small quantities of uric acid with excess accumulation leading to a type of arthritis known as gout.\n\nIn human blood, uric acid concentrations between 3.6 mg/dL (~214µmol/L) and 8.3 mg/dL (~494µmol/L) (1mg/dL=59.48 µmol/L)[3] are considered normal by the American Medical Association, although significantly lower levels are common in vegetarians due to a decreased intake of purine-rich meat.\n\nThe disease gout in humans is associated with elevated blood levels of uric acid . Saturation levels of uric acid in blood may result in one form of kidney stones when the urate crystallizes in the kidney. Some patients with gout eventually get uric kidney stones. Lesch-Nyhan syndrome is also associated with very high serum uric acid levels .
