and Answers All Correct 
 
Identify the equivalence point on the titration curve. 
Define the end point of a titration. - Answer-The equivalence point of a titration is 
reached when the moles of titrant added are stoichiometrically equal to the moles of 
analyte present in solution. This is observed on the titration curve as the point in the 
center of the steepest part of the curve, which correlates to the greatest concentration 
(pH) change per volume of add...
