There are several potential errors of titrations, but I've listed the most common.
First, titrations are a very sensitive method to determine the concentration of an unknown substance. A faulty technique of finding the end point is the most common error. Misreading volumes is also another common human error. Finally, failing to rinse the burette and pipette with the correct solution can lead to a diluted solution, which will change the end point, giving incorrect results.
Hope this helps!
