Question

What and where is the equivalence point?

Is it in the beginning of the experiment or at the reaction point?

Answer 1

I figured out it is the beginning of my chart.

Answer 2

I don't know what your chart looks like but I wouldn't think it would be the beginning of it. Slide down and see what I wrote to Sarah in that long discussion about equivalence point. Or I can help if you still don't understand.
