Astudent performs a titration procedure by adding naoh to a solution that contains h+ ions. she added the indicator, phenolphthalein, to the flask containing the h+ ions. what was the purpose of adding the indicator to the flask?
a. the indicator adds more h+ ions to the solution which allows the titration procedure to proceed faster.
b. the indicator is expected to turn pink when the end point of the neutralization reaction occurs.
c. the indicator was used to determine when the amount of h+ ions was greater than the concentration of oh- ions.
d. because the indicator has the same ph as the naoh, it is used to determine the ph of the titrant.
