CHEMISTRY GLOSSARY
cadmium → kadmij
Cadmium was discovered by Friedrich Strohmeyer (Germany) in 1817. The origin of the name comes from the Latin word cadmia meaning calamine (zinc carbonate, ZnCO3), or from the Greek word kadmeia with the same meaning. It is soft, malleable, blue-white metal. Tarnishes in air, soluble in acids, insoluble in alkalis. Boiling cadmium gives off a weird, yellow-colored vapour that is poisonous. Cadmium can cause a variety of health problems, including kidney failure and high blood pressure. Cadmium is obtained as a by product of zinc refining. The mayor use of cadmium is in electroplating of steel to protect it from corrosion. Also used to make nickel-cadmium batteries. The ability of cadmium to adsorb neutrons has made it of great importance in the design of nuclear reactors. Its compounds are found in paint pigments and a wide variety of intense colours.
carbon → ugljik
Carbon has been known since ancient times. The origin of the name comes from the Latin word carbo meaning charcoal. Graphite form of carbon is a black, odourless, slippery solid. Graphite sublimes at 3825 °C. Diamond form is a clear or colored; an extremely hard solid. C60 is Buckminsterfullerine. Carbon black burns readily with oxidants. Carbon is made by burning organic compounds with insufficient oxygen. There are close to ten million known carbon compounds, many thousands of which are vital to organic and life processes. Radiocarbon dating uses the carbon-14 isotope to date old objects.
meitnerium → meitnerij
Meitnerium was discovered by Peter Armbruster, Gottfried Münzenber and their co-workers at the Heavy Ion Research Laboratory (Gesellschaft für Schwerionenforschung, GSI) in Darmstadt, Germany in 1982. Named in honour of Lise Meitner (1878-1968), the Austrian physicist. It is synthetic radioactive metal. Meitnerium was produced bybombarding bismuth-209 with iron-58.
cathodic protection → katodna zaštita
Cathodic protection is a process in which a structural metal, such as iron, is protected from corrosion by connecting it to a metal that has a more negative reduction half-cell potential, which now corrodes instead of iron. There are two major variations of the cathodic method of corrosion protection. The first is called the impressed current method, and the other is called the sacrificial anode method.
cobalt → kobalt
Cobalt was discovered by Georg Brandt (Germany) in 1735. The origin of the name comes from the German word kobald meaning goblin or evil spirit. It is hard, ductile, lustrous bluish-grey metal. Surfaces stable in air. Reacts over time with dilute acids. It has remarkable magnetic properties. Cobalt occurs in compounds with arsenic and sulfur as in cobaltine (CoAsS) and linneite (Co3S4). Pure cobalt is obtained as a by-product of refining nickel, copper and iron. Used in many hard alloys; for magnets, ceramics and special glasses. Radioactive cobalt-60 is used in cancer therapy.
crucible → lončić za žarenje
Crucible is used for heating small amounts of solid in an oven to very high temperatures. Crucibles are usually made out of porcelain, platinum, nickel or iron.
Curie temperature → Curiejeva temperatura
For a ferromagnetic material, Curie temperature or Curie point (TC) is the critical temperature above which the material becomes paramagnetic. For iron the Curie point is 760 °C and for nickel 356 °C. It was named after the French physicist Pierre Curie (1859-1906).
Mohr’s salt → Mohrova sol
Mohr’s salt is a common name for double salt of iron(II) ammonium sulphate hexahydrate, [Fe(NH4)2 (SO4)2·6H2O].
