Exercise 2 | Chemical Reactivity

For the following compounds give the formulas of their corresponding conjugate acid and base:

H2O, HCO3-, NH3 and HO2-

They are amphoteric compounds: they can react both as an acid and as a base.

H2O: H3O+/H2O and H2O/HO-

HCO3-: H2CO3/ HCO3- and HCO3-/CO32-

NH3: NH4+/NH3 and NH3/NH2-

HO2-: H2O2/ HO2- and HO2-/O22-
