  2. Acetic acid - Wikipedia

    en.wikipedia.org/wiki/Acetic_acid

    The trivial name "acetic acid" is the most commonly used and preferred IUPAC name. The systematic name "ethanoic acid", a valid IUPAC name, is constructed according to the substitutive nomenclature. [8] The name "acetic acid" derives from the Latin word for vinegar, "acetum", which is related to the word "acid" itself.

    en.wikipedia.org/wiki/Ethylenediaminetetraacetic...

    Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid after its own abbreviation, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2.This white, water-insoluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH.

  5. Double bond - Wikipedia

    en.wikipedia.org/wiki/Double_bond

    In chemistry, a double bond is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond. Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist between two different elements: for example, in a carbonyl group between a carbon atom and an oxygen atom.

  6. Disodium pyrophosphate - Wikipedia

    en.wikipedia.org/wiki/Disodium_pyrophosphate

    Disodium pyrophosphate or sodium acid pyrophosphate (SAPP) [1] is an inorganic compound with the chemical formula Na 2 H 2 P 2 O 7. It consists of sodium cations (Na+) and dihydrogen pyrophosphate anions (H2P2O2− 7). It is a white, water-soluble solid that serves as a buffering and chelating agent, with many applications in the food industry.

    Example: 2,2,3-trimethyl- . If there are both double bonds and triple bonds, "en" (double bond) is written before "yne" (triple bond). When the main functional group is a terminal functional group (a group which can exist only at the end of a chain, like formyl and carboxyl groups), there is no need to number it.

  8. Acetate - Wikipedia

    en.wikipedia.org/wiki/Acetate

    An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C

  9. Ammonium sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_sulfate

    Ammonium sulfate is made by treating ammonia with sulfuric acid: 2 NH3 + H2SO4 → (NH4)2SO4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to ...
