CHE SIGNIFICA REAGENT IN INGLESE
Reagente
Un reagente / rieɪdʒənt / è una "sostanza o composto che viene aggiunto ad un sistema per produrre una reazione chimica o aggiunta per vedere se si verifica una reazione". Sebbene i termini reagenti e reagenti siano spesso utilizzati in modo intercambiabile, un reagente è più specificamente una "sostanza che viene consumata nel corso di una reazione chimica". Solventi, anche se sono coinvolti nella reazione, non sono solitamente indicati come reagenti. Analogamente, i catalizzatori non vengono consumati dalla reazione, quindi non vengono descritti come reagenti. Nella chimica organica, i reagenti sono composti o miscele, solitamente composti da molecole organiche inorganiche o piccole, che vengono utilizzate per effettuare una trasformazione su un substrato organico. Esempi di reagenti organici includono il reagente Collins, il reagente di Fenton e il reagente Grignard. Ci sono anche reagenti analitici che vengono utilizzati per confermare la presenza di un'altra sostanza. Esempi di questi sono il reagente di Fehling, il reagente di Millon e il reagente di Tollens.
definizione di reagent nel dizionario inglese
