2. A(n)
is a substance that conducts electricity.
3. The chloride ion (Cl-) is the
base of hydrochloric acid.
4. The formula H3O+ represents the
ion.
5. Label the conjugate acid-base pairs of the following:
a.
NH3(aq) + H2O(l) ↔ NH4+(aq) + OH-(aq)
b.
HNO2(aq) + H2O(l) ↔ H3O+(aq) + NO2-(aq)
c.
HCN(aq) + H2O(l) ↔ H3O+(aq) + CN-(aq)
6. Substances with strong affinities for H+ ions are
7. Strong acids dissociate
