Question

We’re going to titrate formic acid with the strong base, NaOH. There is initially 100. mL of 0.50 M formic acid and the concentration of NaOH is 1.0 M.

5) What volume of NaOH is required to reach the equivalence point? ___________

6) What is the pH at the equivalence point? ___________

7) What is the pOH at the equivalence point? ___________

8) If, instead of NaOH being added, 0.05 moles of HCl is added by __________%

bubbling the gas through the solution. Assume that the volume has

not changed. What is the percent dissociation of formic acid?
