CHEMISTRY GLOSSARY
cerium → cerij
Cerium was discovered by Martin Heinrich Klaproth (Germany) and by Jöns Jacob Berzelius (Sweden) in 1803 and Wilhelm von Hisinger (Germany) in 1814. Named after the asteroid Ceres this discovered two years before the element. It is malleable, ductile, iron-grey metal. Tarnishes in air; reacts easily with water. Dissolves in acids; ignites when heated. Metal ignites and burns readily. Strong reductant. Cerium is most abundant rare earth metal. Found in many minerals like monazite sand [Ce(PO4)]. Its oxides are used in the optics and glass-making industries. Its salts are used in the photography and textile industry. Used in high-intensity carbon lamps and as alloying agents in special metals.
change of state → promjena stanja
Change of state is a physical change which appears when a substance crosses from one state into another. This usually happens because of the change of energy of particles provoked by heating or cooling.
coulometry → kulometrija
Coulometry is a quantitative electrochemical analytical method which is based on measuring the quantity of electricity that has passed and on Faraday’s laws.
covalent compound → kovalentni spoj
Covalent compound is a compound made of molecules - not ions, such as H2O, CH4, Cl2. The atoms in the compound are bound together by shared electrons. Also called a molecular compound.
covering power → prekrivna moć
Covering power is the ability of a plating solution under a set of specified plating conditions to deposit metal on the surfaces of recesses or deep holes. This term suggests an ability to cover, but not necessarily to build up, a uniform coating.
crystal water → kristalna voda
Crystal water is water contained in certain salt crystals. It can be removed by heating. Crystals that contain crystal water are called hydrated and their salts hydrates.
crystallisation → kristalizacija
Crystallisation is process in which the melted substance from a saturated solution turns into solid substance (crystal).
cumulated double bond → kumulirana dvostruka veza
Cumulated double bond in organic compounds is a system of two double bonds on the same atom of carbon (C=C=C)
cycloalkanes → cikloalkani
Cycloalkanes are cyclic saturated hydrocarbons containing a ring of carbon atoms joined by single bonds. They have the general formula CnH2n, for example cyclohexane, C6H12. In general, they behave like the alkanes but are rather less reactive.
Dalton, John → Dalton, John
Dalton, John (1766-1844) British chemist and physicist. In 1801 he formulated his law of partial pressures (Dalton’s law), but he is best remembered for Dalton’s atomic theory, which he announced in 1803. Dalton also studied colour blindness (a condition, once called Daltonism, that he shared with his brother).
