Acid-Base Titrations

a) How will the concentration of NaOH be affected if during the titration some of the solid potassium hydrogen phthalate was spilled during the transfer? Will the concentration of the standardized NaOH increase, decrease, or have no effect?

b) How will the molar mass of an unknown acid be affected if some of the solid remained after the titration was complete? Will the concentration of the molar increase, decrease, or have no effect?

c) How will the concentration of acetic acid in vinegar be affected if the liquid retained in the pipet is blown out? Will the concentration of acetic acid in vinegar increase, decrease, or have no effect?

d) How will the concentration of acetic acid in vinegar be affected if during the titration an air bubble appears in the tip of the buret? Will the concentration increase, decrease, or have no effect?
