Answer: A- Analyte
The end point is the measured volume of analyte solution that yields a change in apperance,usually in the form of change of color in an indicator. A titrant is added to this analyte in order to arrive at the equivalence point,(where the concentration of H+ ions is equal to the concentration of OH- ions) and determine the concentration of the analyte. The end point is an indication that the equivalence point has been achieved.
