CHEMISTRY GLOSSARY
carboxylate ion → karboksilatni ion
Carboxylate ion is gained when carboxylic acid reacts with water.
carboxylates → karboksilati
Carboxylates is a common name for all salts that carboxylic acids yield by reacting with hydroxides, carbonates, bicarbonates and other alkaline reagents.
bismuth → bizmut
Bismuth was discovered by Claude Geoffroy (France) in 1753. The origin of the name comes from the German words Weisse Masse meaning white mass; now spelled wismut and bisemutum. It is hard, brittle, steel-grey metal with a pink tint. Stable in oxygen and water. Dissolves in concentrated nitric acid. Bismuth can be found free in nature and in minerals like bismuthine (Bi2S3) and in bismuth ochre (Bi2O3) Main use is in pharmaceuticals and low melting point alloys used as fuses.
borane → borani
Borane is any of the group of compounds of boron and hydrogen (B2H6, B4H10, B5H9, B5H11...), many of which can be prepared by action of acid on magnesium boride (Mg3B2). Boranes are a remarkable group of compounds in that their structures cannot be described using the conventional two-electron covalent bond model.
boron → bor
Boron compounds have been known for thousands of years, but the element was not discovered until 1808 by Sir Humphry Davy (England) and independently by Joseph-Louis Gay-Lussac (France) and L. J. Thenard (France). The origin of the name comes from the Arabic word buraq and the Persian word burah meaning boraks. It is hard, brittle, lustrous black semimetal. Unreactive with oxygen, water, alkalis or acids. Combines with most metals to form borides. Boron is obtained from kernite, a kind of borax (Na2B4O7·10H2O). High purity boron is produced by electrolysis of molten potassium fluroborate and potassium chloride (KCl). Amorphous boron is used in pyrotechnic flares to provide a distinctive green color and in rockets as an igniter.
Bunsen’s cell → Bunsenov članak
Bunsen’s cell is a primary cell devised by Robert W. Bunsen consisting of a zinc cathode immersed in dilute sulphuric acid and carbon anode immersed in concentrated nitric acid. The electrolytes are separated by a porous pot. The cell gives an e.m.f. of about 1.9 V.
cation exchange → kationski izmjenjivač
Cation exchange is a cationic resin has positive ions built into its structure and therefore exchanges negative ions. In the cation exchange, the side groups are ionised acidic groups, such as (-SO3H, -COOH, -OH) to which cations H+ are attached. The exchange reaction is one in which different cations in the solution displace the H+ from the solid.
conjugated base → konjugirana baza
Conjugated base is a particle which is left after a molecule of acid releases a proton.
