Weak Acid Titration Error Analysis
In a titration of a weak acid with a strong base using phenolphthalein, the calculated acid concentration is consistently higher than the actual value. Assuming correct stoichiometric calculations and properly calibrated equipment, which of the following is the most probable cause of this systematic error?
A
Neglected the effect of the strong base’s concentration
B
Failed to account for the indicator’s color change
C
Overlooked the incomplete dissociation of the weak acid
D
Incorrectly identified the endpoint of the titration
