CHE SIGNIFICA CRYOSCOPY IN INGLESE
Depressione a punto di congelamento
La depressione a punto di congelamento descrive il processo in cui l'aggiunta di un soluto ad un solvente diminuisce il punto di congelamento del solvente. Esempi includono il sale in acqua, l'alcool in acqua o la miscelazione di due solidi come le impurità in un farmaco finemente polverizzato. In questi casi, il composto aggiunto è il soluto e il solido originale può essere considerato come il solvente. La soluzione risultante o la miscela solida-solida ha un punto di congelamento inferiore rispetto al solvente puro o solido. Questo fenomeno è ciò che causa l'acqua di mare (una miscela di sale (e altre cose) in acqua) a rimanere liquido a temperature inferiori a 0 ° C, il punto di congelamento dell'acqua pura.
definizione di cryoscopy nel dizionario inglese
La definizione di crioscopia nel dizionario è la determinazione dei punti di congelamento, specialmente per la determinazione dei pesi molecolari misurando l'abbassamento del punto di congelamento di un solvente quando viene aggiunta una quantità nota di soluto.
