WebMay 16, 2024 · 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.

WebThere is also parallax error where the angle of view can lead to different readings. This is where technique comes in and also experience with the equipment. One way to somewhat cancel out these type of random errors is is to take two readings and take the difference. http://blog.dwyer-inst.com/2024/03/16/what-is-parallax-error-and-how-can-i-avoid-it/
