Question

identify the arrenius bases, bronsted-lowlry bases, and lewis bases in-
a. NaOH(s) ->Na+(aq)+OH-(aq)
b.HF(aq)+ H2O(l) -> F-(aq)+H3O+(aq)
c.H+(aq)+NH3(aq) -> NH+4(aq)

Answer 1

Arrhenius Acid: Increases H+ concentration
Arrhenius Base: Increases OH- concentration
Bronsted-Lowry Acid: Donates a proton (H+)
Bronsted-Lowry Base: Accepts a proton
Lewis Acid: Accepts an electron pair
Lewis Base: Donates an electron pair

a. The Arrhenius definitions work the best here: NaOH is the base, which splits into the conjugate acid (Na+) and conjugate base (OH-).

b. Standard Arrhenius definitions.

c. Arrhenius doesn't really apply here, Bronsted-Lowry is better for this case.

I hope you can figure out which is the acid and which is the base on your own, given the definitions of each.
