Question: why is an additional 3.00 mL of NaOH added to the reaction solution, beyond what is required for neutralization?
ANswer: D. To ensure that NaOH is present in excess.
Titration requires small amount of excess of hydroxide ions (OH−) in solution. which react with indicator (phenolphthalein molecules) and changing it from the acidic form to the basic form.
