Given the following information: benzoic acid = C6H5COOH formic acid = HCOOH HCO

Question

Given the following information:

benzoic acid = C6H5COOH

formic acid = HCOOH

HCOOH is a stronger acid than C6H5COOH

(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.084 M aqueous benzoic acid and sodium formate are mixed. It is not necessary to include states such as (aq) or (s). Use HCOO- as the formula for the formate ion.

_____ + _____ = ______ + ______

(2) Which is the strongest base, C6H5COO- or HCOO- ?

(3) At equilibrium (products or reactants) the will be favored?

Explanation / Answer

HCOOH is a stronger acid than C6H5COOH.

Hence formate ion (HCOO-) is weak base than C6H5COO-.

1) net ionic equation is

C6H5COOH + HCOO- <..............> HCOOH + C6H5COO-

2) C6H5COO- is the strongest base.

3) At equilibrium  reactants the will be favored.
