Chemistry


We’re going to titrate formicacid with the strong base, NaOH. There is initially 100. mL of 0.50M formic acid and the concentration of NaOH is 1.0 M. Allwork MUST beshown to receive credit. See announcement for duedate.

a) Whatis the initial pH of the formic acid solution?​​​___________

b) What isthe percent ionization under initial conditions?​​​__________%

c) After theaddition of 10 mL of NaOH, what is the pH?​​      ___________

d) After theaddition of 25 mL of NaOH, what is the pH? Think​      ___________

  aboutwhere in the titration this brings you.

e) Whatvolume of NaOH is required to reach the equivalencepoint?  ​       ​___________

f) What is thepOH atthe equivalence point?    ​      ​  ___________

g) What isthe pH at the equivalence point?   ​  ​___________

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

bubbling the gas through thesolution. Assume that the volume has not changed. What is the percent dissociationof formic acid?
