what are some possible systematic errors of titration?

Answer 1

During a titration experiment systematic errors such as the calibration of the burette and glassware, the quality of the reagents and determination of the end point. The largest and most important error is the determination of the end point because it is usually done visually using a chemical indicator. This occurs when you think you see the end of the reaction when the color changes but the equivalance point was already passed and this lag creates the error. That means more of the titrant is delivered than is needed resulting in a higher concentration in the calculations.

Answer 2

There are many possible sources of systematic error for titration:

1) Color changes of indicators are not instant, they are gradual over time. Thus, it is quite literally impossible to eye the exact moment when you reach the equivalence point.

2) Endpoint and equivalence point are different.

3) The glassware used in the titration are miscalibrated or not calibrated at all.
