,A-- Bronsted-Lowry baseis defned as anything that

a**ets H1+ions.

Base example:

NH3 (aq)+ H2O NH/+(aq)+ OH(aq)

! " 1.0'1 In this e'a%le NH3is a &ase and H2O is a*ting as an

a*id. NH/+is the *on$gate a*id o the &ase NH3 and

OHis the *on$gate &ase o the a*id H2O. A *o%o$nd that *an a*t as either an a*id or a &ase

s$*h as the H2O in the a&o#e e'a%les is *alled

amphiprotic.
