Question
A student used a titration to determine the concentration of acetic acid in vinegar. The vinegar was first diluted with distilled water and samples of the diluted solution were then titrated with sodium hydroxide solution. The titration value was more than expected. Which of the following actions can account for this observation? *
A- The inside of the volumetric flask used to prepare the diluted vinegar was rinsed with water and not dried properly prior to use.
B- The sodium hydroxide solution had been allowed to stand exposed to air for a long time prior to the titration.
C- The inside of the burette used to deliver the sodium hydroxide solution was rinsed with water and not dried properly prior to use.
D- None of these actions will increase the titration value.
E- All these actions will increase the titration value.
