Titration Question - How many mL of 0.0350M NaOH are required to titrate 40.0 mL of 0.0350 M HNO3 solution to its equivalence point?
There is a shortcut to the answer which I will include at the end, but this is the "long way around".
Both species are strong, i.e both the Nitric acid and the Sodium hydroxide will completely dissociate in aqueous solution.
For a "Strong-Strong" titration, the equivalence point will be exactly at
They react in a 1:1 ratio:
So to get to the equivalence point an equal amount of mol of
Using the concentration formula we can find the moles of
(40 ml=0.04 liters=
So we need an equal amount of moles of
Because we know they react in a 1:1 ratio, and they are of equal concentration, the volume needed to neutralize a solution 40ml of a given concentration
