Come si dissocia NH4Cl in acqua?

L’idrolisi del cloruro d’ammonio

  1. Quanti grammi di cloruro d’ammonio occorre sciogliere in 600 ml di acqua per avere una soluzione a pH = 5, sapendo che la Kb dell’ammoniaca è 1,8×10-5?
  2. Grazie.
  3. Il cloruro d’ammonio è un sale che, una volta sciolto in acqua, dissocia in ioni:
  4. NH4Cl → NH4+ + Cl–

A cosa serve il cloruro di ammonio?

Il cloruro di ammonio è un sale naturale, ottenuto industrialmente dall’acido idroclorico e dall’ammoniaca. E’ un composto usato nel settore alimentare principalmente per la sua funzione di regolatore dell’acidità.

Come capire che è una soluzione tampone?

Caratteristiche. La caratteristica delle soluzioni tampone è che il pH di tali soluzioni rimane pressoché invariato in seguito all’aggiunta di piccole quantità di acido o basi forte. Per spiegare il meccanismo di funzionamento consideriamo una soluzione costituita da acido acetico e da acetato di sodio.

Quali sono le soluzioni tampone più usate in biologia?

Negli organismi pluricellulari il fluido all’interno della cellula e i fluidi che circondano le cellule hanno un pH caratteristico e praticamente costante che viene mantenuto da soluzioni tampone biologiche come il sistema diidrogeno fosfato e il sistema acido carbonico. …
