Proton transfer reactions - amphiprotic and amphoteric species Flashcards
1
Q
Amphiprotic species definition
A
Species that can act both as proton donors and acceptors
2
Q
Amphoteric definition
A
Species that can act as either acids or bases
3
Q
Amphiprotic / amphoteric rule
A
All amphiprotic species are amphoteric - when they donate a proton they are acting as an acid, and when they accept a proton they are acting as a base
4
Q
Examples of amphiprotic species
A
Water, amino acids
5
Q
Amphoteric species example
A
Aluminium oxide (Al2O3)
