Question: A solution is prepared from 0.150 mol of formic acid and enough water to make 0.425 L of solution. a. Determine the concentrations of H3O+

A solution is prepared from 0.150 mol of formic acid and enough water to make 0.425 L of solution.
a. Determine the concentrations of H3O+ and HCOO in this solution.
b. Determine the H3O+ concentration that would be necessary to decrease the HCOO concentration above by a factor of 10. How many milliliters of 2.00 M HCl would be required to produce this solution? Consider that the solution was made by combining the HCl, the HCOOH, and enough water to make 0.425 L of solution.
c. Qualitatively, how can you account for the differences in the percentage dissociation of formic acid in parts a and b of this problem?
