An Entity of Type: Part113809207, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In chemistry, a protic solvent is a solvent that has a hydrogen atom bound to an oxygen (as in a hydroxyl group −OH), a nitrogen (as in an amine group −NH or −NH−), or fluoride (as in hydrogen fluoride). In general terms, any solvent that contains a labile H+ is called a protic solvent. The molecules of such solvents readily donate protons (H+) to solutes, often via hydrogen bonding. Water is the most common protic solvent. Conversely, polar aprotic solvents cannot donate protons but still have the ability to dissolve many salts. Methods for purification of common solvents are available

  • Protické rozpouštědlo je rozpouštědlo, které má atom vodíku navázaný na kyslík (například v hydroxylové skupině), dusík (například v aminové skupině) nebo fluor (jako je fluorovodík). Obecně vzato jsou protická taková rozpouštědla, která mohou odštěpit vodíkový kation (H+). Jejich molekuly snadno dodávají protony (H+) rozpuštěným látkám, často prostřednictvím vodíkových vazeb. Aprotická polární rozpouštědla oproti tomu nemohou dodávat protony, ovšem i tak rozpouštějí mnohé soli. (cs)
  • Un solvant protique est un solvant polaire possédant au moins un hydrogène susceptible d'intervenir dans des liaisons hydrogène. Ceci se rencontre lorsqu'un hydrogène est lié à un hétéroatome. Il s'agit de l'eau, du méthanol ou de l'acide acétique. Ce type de solvant est alors donneur ou accepteur de liaison hydrogène. L'UICPA recommande d'employer le terme solvant protogène plutôt que solvant protique et le définit comme un solvant capable d'agir comme donneur de proton, pris au sens acide de Brönsted. (fr)

  • In chimica, un solvente protico è un solvente la cui struttura molecolare presenta un atomo di idrogeno dissociabile come ione H+. Tale atomo di idrogeno è generalmente legato ad un atomo di ossigeno o di azoto in un gruppo amminico, ma anche l'acido fluoridrico può essere considerato un solvente protico. In generale, un solvente protico è un solvente capace di cedere uno ione H+; un solvente che non ha questa capacità (come ad esempio la dimetilformammide) è invece un solvente aprotico. Tra le caratteristiche comuni ai solventi protici si annoverano le seguenti * sono in grado di formare legami idrogeno * possiedono un idrogeno acido (anche se possono essere acidi molto deboli) * stabilizzano gli ioni per solvatazione Esempi di solventi protici sono l'acqua, il metanolo, l'etanolo, l'acido formico, l'acido fluoridrico e l'ammoniaca; in generale tutti gli alcoli e gli acidi carbossilici a basso peso molecolare. I solventi protici favoriscono le reazioni di tipo SN1. (it)
