Given the balanced equation representing a reaction:

NH3(g) + H2O(l) ==>NH4+(aq) + OH-(aq)

According to one acid-base theory, the NH3(g) molecules act as

(1) an acid because they accept H+ ions

(2) an acid because they donate H+ ions

(3) a base because they accept H+ ions

(4) a base because they donate H+ ions

Verified Answer :

PhyCS

(2) a base because they accept H+ ions. NH3 is the conjugate base of NH4+.
