Given the following information:
| formic acid | HCOOH | Ka = 1.8×10-4 |
| triethylamine | (C2H5)3N | Kb = 5.2×10-4 |
(1) Write the net ionic equation for the reaction
that occurs when equal volumes of 0.167
Maqueous formic acid and
triethylamine are mixed. It is not necessary to
include states such as (aq) or (s). Use HCOO- as
the formula for the formate ion.
-reactant or product favored?
-pH is >, <, = to 7?
