Using the equivalence point volumes determined from the expanded titration graph or the first derivative graph, the volume of acetic acid titrated (pipet volume), and the concentration of your diluted NaOH standard solution, calculate the concentration of the unknown acid solution. Equivalence point volume= 18.5 Concentration of diluted NaOH= 0.19709 Volume acetic acid= 5 mL (diluted in 70 mL dH20 but I guess it does not matter?)
