identify the three linear data ranges (before the equivalence point, equivalence point, after the equivalence point) and calculate the equivalence

1. identify the three linear data ranges (before the equivalence point, equivalence point, after the equivalence point) and calculate the equivalence point( midpoint of C and D)
2. based on the volume of NaOH added to reach the equivalence point and the known concentration of NaOH, calculate moles of NaOH added to reach the equivalence point.
3. calculate the moles of HCl titrated and the actual concentration of HCl
4. identify the colorimetric end point volume from titration data. calculate the percent difference in volume of NaOH between pH meter based equivalence point and the indicator based end point. Assume the equivalence point volume is the accepted volume.
5. at the equivalence point should the solution be acidic, neutral or basic? explain

0.100 M standard NaOH

0.05 M HCl (50 ml)

5 drops of phenolphthalein
