alleryAccording to the Bronsted-Lowry theory, an acid is:
AAn electron-pair acceptor (this is Lewis acid)
BA hydroxide donor (Arrhenius base)
CAn electron-pair donor (this is Lewis base)
DA proton (H+) donor in solution
Answer & Solution
Correct answer: D. A proton (H+) donor in solution
BRONSTED-LOWRY acid = PROTON (H+) DONOR.
Bronsted base = proton acceptor.
The Lewis definition uses electron pairs.
Arrhenius is the most restrictive (only aqueous H+/OH−).
