Acid-Base Titration<BLURT>

Acid-Base Titration


1. In an acid-base titration, when does the equivalence point occur? A. When all the moles of H+ in the base solution have reacted with all the moles of OH- added from the buret.
B. When the moles of H+ in the acid solution equals the moles of H+ added from the buret.
C. When all the moles of H+ in the acid solution have reacted with all the moles of OH- added from the buret.
D. When the moles of OH- in the acid solution equals the moles of OH- added from the buret.
