Three Questions Acid/Base Equilibrium I
1. Write balanced equations that describe the following reactions.
a. the dissociation of perchloric acid in water.
b. the dissociation of propanoic acid (HC3H5O2) in water.
c. the dissociation of ammonium ion in water.
2. For each of the following aqueous reactions, identify the acid, the base, the conjugate base,
and the conjugate acid.
a. H2O (l) + H2CO3 (aq) ⇄ H3O+ (aq) + HCO3¯ (aq)
b. C5H5NH+ (aq) + H2O (l) ⇄ C5H5N (aq) + H3O+ (aq)
c. HOCl (aq) + C6H5NH2 (aq) ⇄ OCl¯ (aq) + C6H5NH3+ (aq)
3. Use the Ka table in your book to list the following in order of increasing acid strength:
HNO2, HCl, HC2H2ClO2, HCN
