Which salt is formed when aqueous NH4OH reacts with HNO3?
A

B
NaNO3
C
NH4NO3
D
KNO2
Verified step by step guidance1
Identify the reactants: aqueous NH4OH (ammonium hydroxide) is a weak base, and HNO3 (nitric acid) is a strong acid.
Recognize that when an acid reacts with a base, they undergo a neutralization reaction to form a salt and water.
Write the neutralization reaction: $\mathrm{NH_4OH + HNO_3 \rightarrow NH_4NO_3 + H_2O}$.
Understand that the salt formed consists of the cation from the base (NH4\textsuperscript{+}) and the anion from the acid (NO3\textsuperscript{−}), resulting in ammonium nitrate (NH4NO3).
Confirm that the other options either contain incorrect ions or do not correspond to the products of this acid-base reaction.
