Which of the following terms is INCORRECTLY defined?

A) titration error: the difference between the end point and the equivalent point
B) direct titration: titrant is added to analyte until reaction is complete
C) equivalent point: volume of titrant added in excess of the end point to change a physical property of the analyte solution
D) blank titration: titration performed without analyte to calculate titration error
E) standardization: titration of a known amount of analyte to determine the concentration of the titrant
