I The endpoint of an acid-base titration is defined as the point where O A. The amount (moles) of acid and base present are equivalent and a physio-chemical change occurs. O B. All the base added from the burette is used up. O C. Excess titrant is present. O D. The number of moles of acid and base are equal.
