CHEMISTRY GLOSSARY
allomorphism → alomorfija
Allomorphism is the existence of chemical substances with same chemical composition in two or more crystalline forms. See Polymorphism.
acetal → acetal
Acetals are organic compounds having the structure R2C(OR’)2 (R’ ≠ H). They are organic compounds formed by addition of alcohol molecules to aldehyde or ketone molecules. Originally, the term was confined to derivatives of aldehydes (one R = H), but it now applies equally to derivatives of ketones (neither R = H ). Mixed acetals have different R’ groups. The formation of acetals is reversible; acetals can be hydrolysed back to aldehydes (ketone) in acidic solutions.
Acetal, 1,1-diethoxyethane (CH3CH(OC2H5)2), is an organic compound, pleasant smelling, formed by addition of ethyl alcohol to ethanal (acetaldehyde). It is used as a solvent and in synthetic organic chemistry.
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.
activation energy → energija aktivacije
Activation energy (Ea) is the energy that must be added to a system in order for a process to occur, even though the process may already be thermodynamically possible. In chemical kinetics, the activation energy is the height of the potential barrier separating the products and reactants. It determines the temperature dependence on the reaction rate.
