Answer is: 2.NaNO₃.
Balanced chemical reaction of neutralization:
HNO₃(aq) + NaOH(aq) → NaNO₃(aq) + H₂O(l).
Ionic reaction:
H⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + OH⁻(aq) → Na⁺(aq) + NO₃⁻(aq) + H₂O(l).
Net ionic reaction: H⁺(aq) + OH⁻(aq) → H₂O(l).
Neutralization is reaction in which an acid and a base react quantitatively with each other. In this reaction, there are no acids and bases, only salts.
