Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question 3 please thank you

Titration
1
To determine the concentration of HNO,(aq), a student
titrates a 100. mL sample of the acid solution with 0.100 M
KOH(aq). The neutralization reaction is represented below.
HNO,(aq) + OH (aq) → NO, (aq) + H,O(1)
Draw the Lewis structure of HNO2 and identify the
hybridization around the nitrogen atom.
2
If 20.0 mL of KOH(aq) is required to reach the
equivalence point (end point) of the titration, determine
the initial concentration of the HNO, solution. Show
work.
3
During the titration, after a volume of 15 mL of 0.100 M
KOH(aq) has been added, which species, HNO,(aq) or
NO, (aq), is present at a higher concentration in the solution?
Justify your answer.
