Sodium borohydride
Reducing agent used in the prepn. of modified hop extract. BH4? is an excellent ligand for metal ions. Such borohydride complexes are often prepared by the action of NaBH4 (or the LiBH4) on the corresponding metal halide, e.g. Zr(BH4)4.; Sodium borohydride is a particularly dangerous laboratory reagent. It is highly corrosive, and will cause burns upon contact with any area of the body. It is harmful if swallowed, inhaled or absorbed through the skin. It is highly flammable and will react with water.; Sodium borohydride is an odorless white to gray-white microcrystalline powder which often forms lumps. It is soluble in water, with which it reacts vigorously.; Sodium borohydride is highly reactive, and supports combustion. It is a flammable solid. It can ignite in air in the presence of an open flame, and will continue to burn as hydrogen is evolved. It can react with water and steam to produce hydrogen, which is flammable. An explosion can occur by spontaneous ignition of the gases released from a saturated solution of sodium borohydride in dimethylformamide at 17 °C.; Sodium borohydride, also known as sodium tetrahydroborate, has the chemical formula NaBH4. This white solid, usually encountered as a powder, is a specialty reducing agent used in the manufacture of pharmaceuticals and other organic and inorganic compounds. It is soluble in methanol and water, but reacts with both in the absence of base. Sodium borohydride is found in alcoholic beverages. Reducing agent used in the prepn. of modified hop extract
Flourine
F2 (37.9968064)
Fluroine, also known as bifluoriden or f2, is a member of the class of compounds known as homogeneous halogens. Homogeneous halogens are inorganic non-metallic compounds in which the largest atom is a nobel gas. Fluroine can be found in potato, which makes fluroine a potential biomarker for the consumption of this food product. Among the elements, fluorine ranks 24th in universal abundance and 13th in terrestrial abundance. Fluorite, the primary mineral source of fluorine which gave the element its name, was first described in 1529; as it was added to metal ores to lower their melting points for smelting, the Latin verb fluo meaning "flow" gave the mineral its name. Proposed as an element in 1810, fluorine proved difficult and dangerous to separate from its compounds, and several early experimenters died or sustained injuries from their attempts. Only in 1886 did French chemist Henri Moissan isolate elemental fluorine using low-temperature electrolysis, a process still employed for modern production. Industrial production of fluorine gas for uranium enrichment, its largest application, began during the Manhattan Project in World War II . Fluorine is the chemical element with atomic number 9, represented by the symbol F. It is the lightest halogen. Under normal conditions, elemental fluorine is a yellow-green gas consisting of diatomic molecules, F2. Fluorine is found in many foods, some of which are pear, almond, garden rhubarb, and cabbage.
