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.
