Answer:

a) Acid = H2O  Conjugate Base = OH-  Base = C5H5N  Conjugate Acid = C5H5NH+

b) Acid = NH4+  Conjugate Base = NH3  Base = OH-  Conjugate Acid = H2O

Explanation:

The Bronsted-Lowry definition of an

- acid = proton donor (donates H+ ion)

- base = proton acceptor (accepts H+ ion)

a) H2O is an acid because it donates an H+ ion and turns into OH-, making OH- the conjugate base of H2O. Because C5H5N accepts the proton, it is the base and it becomes C5H5NH+, which is the conjugate acid.

b) NH4+ is an acid because it donates an H+ ion and turns into NH3, making NH3 the conjugate base of NH4+. Because OH- accepts the proton, it is the base and it becomes H2O, which is the conjugate acid.
