Lab instructors usually answer the inquiry with remarks such as “Looks like you have overshot the endpoint” or “Perhaps, you should check the amount of the indicator and redo.” Titration ColorDarts (TCD) is aimed to enable the learners to identify the probable errors in their titration experiment independently.
