How do you figure equivalence volume? Do I add up all of the additions during my lab up to the point I am measuring (color change) to get the equivalence volume? I guess I am confused when it says calculate the equivalence volume, maybe it is very simply.

Answer 1

To be honest with you, I've never heard the term equivalence volume used. However, my best educated guess is that the equivalence volume is the volume of a titrate required to reach the equivalence point. By the way, and this is a little picky, when you titrate with an indicator, the point at which the indicator changes color is the END POINT. You HOPE that the end point and the equivalence point are the same.

Answer 2

Thanks. That is exactly what I thought it was.
