Q

Bronsted-Lowry defined an acid as

Proton Donor
Proton Acceptor
Electron Pair Donor
Electron Pair Acceptor

A

Proton Donor

According to Bronsted-Lowry theory, acid is a substance which donates an H+ ion or a proton and forms its conjugate base and the base is a substance which accepts an H+ ion or a proton and forms its conjugate acid.
