CHEMISTRY GLOSSARY

acid-base titration    →   kiselo-bazna titracija

Acid-base titration is an analytical technique in volumetric analysis, where an acid of known concentration is used to neutralise a known volume of a base, and the observed volume of the acid required is used to determine the unknown concentration of the base. An acid-base indicator is used to determine the end-point of the titration.

manganometry    →   manganometrija

Manganometry is a quantitative oxidimetric method based on measurement of potassium permanganate (KMnO₄) spent for an oxidation of the matter in question.

photoelectric effect    →   fotoelektrični efekt

Photoelectric effect is the complete absorption of a photon by a solid with the emission of an electron. The energy of a photon (hν) is

teratogen    →   teratogen

Teratogen is a drug or other substance capable of interfering with the development of an embryo fetus that may lead to birth defects or developmental malformations.

thermochemical equation    →   termokemijska jednadžba

Thermochemical equation is a compact equation representing a chemical reaction that describes both the stoichiometry and the energetics of the reaction. For example, the thermochemical equation

means When one mole of gaseous methane is burned in two moles of oxygen gas, one mole of carbon dioxide gas and 2 moles of steam are produced, and 2 220 kJ of heat are released.

volt    →   volt

Volt (V) is the SI derived unit of electric potential. One volt is the difference of potential between two points of an electric conductor when a current of 1 ampere flowing between those points dissipates a power of 1 watt. It was named after the Italian physicist Alessandro Volta (1745-1827).
