1) Write a balanced equation as in footnote 2 for the neutralization of formic acid with sodium hydroxide?

2) If an air bubble is present initially in the tip of the vinegar buret, but 'disappears' during the course of the titration, how would this affect your calculations for the concentration of acetic acid (larger, smaller, no effect)? Explain your answer.

3) Explain how the indicator for phenolphthalein works. Why does it turn pink only when nHAc=nNaOH?

4) Using a pipet 20ml of acetic acid is titrated with 0.2000 M solution of NaOH. The initial reading in the NaOH buret is 1.12ml. When the solution is very light pink the buret reads 24.37ml. What is the concentration of acetic acid both in M and in Percentage m/v.

5) Remembering that sulfuric acid (H2SO4) is a diprotic acid (i.e. has teonacidic H's) write the equation for its neutralization reaction with NaOH. How many ml of a 0.200M solution of NaOh would be required to neutralize 25.00 mL of a 0.100M solution of sulfuric acid?
