Remember you should always repeat whole process at least 3 times to ensure you have an accurate result, as there is the potential for both random and systematic errors to affect your results.

Why must titration be repeated?

A titration is repeated at least three times in order to provide a statistically valid answer. It's a form of volumetric analysis to uncover the concentration of a substance, and the readings should all be within a very small number of units of one another.

What happens if you over titrate?

If you overshoot the endpoint in titration of the KHP, an error will happen in your calculations for the molarity of NaOH you are standardizing. ... Adding more of the base needed to reach the equivalence would mean you have higher volume which will make the calculated concentration of NaOH lesser.
