Stoich and End Points
Why is it important for an end point to be within 1 pH unit of the stoichiometric point?

It is because the closer the end points are to the equivalence point, we have a smaller indicator error and the more accurate the titration will be. I think we both agree we like a more accurate result and less error when we are doing scientific research right?

Re: Stoich and End Points
Also once you are that close, even the smallest addition of the titrant(including a single drop) can shift the ph may past the stoichiometric point.
Re: Stoich and End Points
The key is to find the point at which the acid or base of the sample and the respective acid or base of the titration reach a balance (stoichiometric point), thus it would be important that the end point be close to the stoichiometric point in an accurate reaction.
