What is the numerical relationship between the volume of base added to reach the first endpoint and the volume added to reach the final endpoint in the titration of a diprotic acid? What is the relationship for a triprotic acid?

If you are titrating with the same concn, then v1 = v2 = v3. Reasonably, if it takes a particular volume to remove the 1st H, then it must take twice that much to remove the second and three times that much to remove the third ond.
