We are asked to determine whether the following statement concerning the given titration is true or false.
A larger volume of NaOH(aq) is needed to reach the equivalence point in the titration of HNO3.
1. Titration of 25.0 mL of 1.0 M HNO3 with 0.100 M NaOH solution
The reaction for this titration can be represented by:
HNO3 + NaOH → NaNO3 + H2O
In the reaction HNO3, a strong acid, will react with NaOH, a strong base to form a neutral solution.
At the equivalence point of the reaction, hydronium (H+) and hydroxide (OH-) ions will react to form water, leading to a pH of 7.
This is true for all strong acid and strong base reactions.
Recall that at the equivalence point of a titration:
