Accademico IELTS (Banda 8 e Superiore) - Chemistry

a substance that is dissolved in a solvent, resulting in a solution

soluto

a substance that takes part in and undergoes a chemical reaction, leading to the formation of new products

reagente, sostanza reattiva

(chemistry) a substance that causes a chemical reaction to happen at a faster rate without undergoing any chemical change itself

Catalyst

the acceleration or facilitation of a chemical reaction by a substance (catalyst) that remains unchanged at the end of the reaction

catalisi, accelerazione chimica

a chemical bond where atoms share electrons to form a stable molecule

legame covalente, legame covalente

any of two or more compounds having the same molecular formula but different arrangements of atoms and, consequently, different properties

isomero

a large molecule composed of repeating structural units, or monomers, covalently bonded together in a chain-like structure

polimero

a molecule that can chemically bond with other molecules to form a polymer

monomero

a compound composed of hydrogen and carbon atoms, with the simplest form being alkanes, alkenes, or alkynes

idrocarburo

a chemical compound derived from the reaction between an alcohol and an organic acid, typically with the elimination of water

estere

an organic compound with a carbonyl group (C=O) bonded to a hydrogen atom and another carbon atom, commonly found in essential oils and used in various chemical processes

aldeide

a compound with a hydroxyl group (-OH) attached to a carbon atom, widely used as solvents, fuels, and in pharmaceutical and chemical synthesis

alcol, alcolici

an organic compound with a carbonyl group (C=O) bonded to two carbon atoms, commonly found in solvents, pharmaceuticals, and flavorings

chetone

a chemical reaction where electrons are transferred between substances

reazione di ossidoriduzione, reazione redox

the concentration of a solute in a solution, measured in moles per liter (mol/L or M)

molarità

a substance that, when dissolved in a solution, produces ions and enables the conduction of electric current

elettrolita

a thermodynamic quantity representing the total heat content of a system, commonly denoted as H

entalpia

a thermodynamic measure of the degree of disorder or randomness in a system, denoted by S

entropia

a mixture where small particles of one substance are evenly dispersed in another substance, typically intermediate in size between solution and suspension particles

colloide

the gradual destruction of materials by chemical reaction, usually of metals

corrosione

any substance with a pH of more than seven that neutralizes acids creating salt and water

alkali
