Is Sodium Hydroxide a Bronsted-Lowry Base?
All Arrhenius acids and bases are also Bronsted-Lowry bases.
According to this website,


  The Bronsted-Lowry theory doesn't go against the Arrhenius theory in any way - it just adds to it.


Remember, when we write NaOH (aq), what we really mean is Na+ (aq) and OH- (aq). Sodium hydroxide is a Bronsted-Lowry base because the hydroxide ions that are a part of sodium hydroxide accept protons.
