Bromide is present in typical seawater (35 PSU) with a concentration of around 65 mg/L, which is about 0.2% of all dissolved salts. Seafood and deep sea plants generally have higher levels than land-derived foods. Bromargyrite—natural, crystalline silver bromide—is the most common bromide mineral known but is still very rare. In addition to ...
Hundreds of known organobromine compounds are generated by terrestrial and marine plants and animals, and some serve important biological roles. [12] As a pharmaceutical, the simple bromide ion (Br −) has inhibitory effects on the central nervous system, and bromide salts were once a major medical sedative, before replacement by shorter ...
Plants in the Bromeliaceae are widely represented in their natural climates across the Americas. One species ( Pitcairnia feliciana ) can be found in Africa. [ 30 ] They can be found at altitudes from sea level to 4,200 meters, from rainforests to deserts . 1,814 species are epiphytes , some are lithophytes , and some are terrestrial.
These may be metal salts containing bromide ion such as potassium bromide, or more covalent bromides of metals or nonmetals such as tantalum(V) bromide or phosphorus tribromide. See also [ edit ]
Bromelain is present in all parts of the pineapple plant (Ananas sp.), [4] but the stem is the most common commercial source, [4] [5] presumably because usable quantities are readily extractable after the fruit has been harvested.
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...
Bromide ions, as provided by salts like sodium bromide, function as a nucleophiles in the formation of organobromine compounds by displacement. [ 4 ] An example of this salt mediated bromide displacement is the use of Copper(II) bromide on ketones : [ 5 ] [ 6 ]
