[20.1] brønsted-lowry acids and bases Flashcards
1
Q
describe the arrhenius model of acids and bases
A
- acids dissociate and release H+ ions in aqueous solution
- alkalis dissociate and release OH- ions in aqueous solution
- H+ ions are neutralised by OH- ions to form water
2
Q
what is an alkali?
A
a soluble base
3
Q
what is a brønsted-lowry acid?
A
a proton donor
4
Q
what is a brønsted-lowry base?
A
a proton acceptor
5
Q
what is a conjugate acid?
A
a species formed from a brønsted-lowry base by the addition of a proton
6
Q
what is a conjugate base?
A
a species formed from a brønsted-lowry acid by the loss of a proton
7
Q
what does a conjugate acid-base pair contain?
A
two species that can be interconverted by transfer of a proton
8
Q
what do monobasic, dibasic and tribasic acids refer to?
A
the number of hydrogen ions in the acid that can be replaced per molecule in an acid-base reaction
