Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

Which of the following terms is INCORRECTLY
defined?
titration error: the difference between the end
point and the equivalent point
blank titration: titration performed without analyte
to calculate titration error
standardization: titration of a known amount of
analyte to determine the concentration of the
titrant
direct titration: titrant is added to analyte until
reaction is complete
equivalent point: volume of titrant added in excess
of the end point to change a physical property of
the analyte solution
