Folin–Ciocalteu reagent. The Folin–Ciocâlteu reagent (FCR) or Folin's phenol reagent or Folin–Denis reagent, is a mixture of phosphomolybdate and phosphotungstate used for the colorimetric in vitro assay of phenolic and polyphenolic antioxidants, also called the gallic acid equivalence method (GAE). [1] It is named after Otto Folin ...
Transition metal carboxylate complexes are coordination complexes with carboxylate (RCO 2−) ligands. Reflecting the diversity of carboxylic acids, the inventory of metal carboxylates is large. Many are useful commercially, and many have attracted intense scholarly scrutiny. Carboxylates exhibit a variety of coordination modes, most common are ...
Sodium molybdate has the advantage in that the dosing of lower ppm's of molybdate allow for lower conductivity of the circulating water. Sodium molybdate at levels of 50-100 ppm offer the same levels of corrosion inhibition as sodium nitrite at levels of 800+ ppm. By utilizing lower concentrations of sodium molybdate, conductivity is kept at a ...
Sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O), also known as washing soda, is the most common hydrate of sodium carbonate containing 10 molecules of water of crystallization. Soda ash is dissolved in water and crystallized to get washing soda. It is one of the few metal carbonates that is soluble in water.
Molybdic acid. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Molybdic acid refers to hydrated forms of molybdenum trioxide and related species. The monohydrate (MoO 3 ·H 2 O) and the dihydrate (MoO 3 ·2H 2 O) are well characterized. They are yellow diamagnetic solids.
Sodium percarbonate or sodium carbonate peroxide is a chemical substance with formula Na2H3CO6. It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na2CO3 · 3 H2O2. It is a colorless, crystalline, hygroscopic and water-soluble solid. [3]
Molybdenum is an essential element in most organisms; a 2008 research paper speculated that a scarcity of molybdenum in the Earth's early oceans may have strongly influenced the evolution of eukaryotic life (which includes all plants and animals). [1] At least 50 molybdenum-containing enzymes have been identified, mostly in bacteria.
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.
