In a titration, which volume is most accurate for determining the exact amount of a neutralized species, the endpoint volume or the equivalence point volume? Why?
The volume of the titrant added to the analyte is the most critical thing in titration because, this parameter helps you to determine the unknown concentration of the analyte or the unknown amount of analyte.
If you add more or less volume of titrant, then you will end up in wrong calculation of analyte concentration. This gives you wrong estimation of amount of the analyte present.
Hence, determination of accurate volume at end point or equivalence point is important.

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...

In a titration that initially contains carbonate and bicarbonate, the volume of titrant required to reach the first equivalence point is less than that required to titrate from the first equivalence point to the second. Explain Why?
