Verified step by step guidance

Identify the compound given: ammonium nitrate, which has the chemical formula $\mathrm{NH_4NO_3}$.

Recall that ammonium nitrate is an ionic compound composed of the ammonium ion and the nitrate ion.

Write the dissociation equation for ammonium nitrate in water: $\mathrm{NH_4NO_3 (s) \rightarrow NH_4^+ (aq) + NO_3^- (aq)}$.

Recognize that $\mathrm{NH_4^+}$ is the ammonium ion, a positively charged polyatomic ion, and $\mathrm{NO_3^-}$ is the nitrate ion, a negatively charged polyatomic ion.

Conclude that when $\mathrm{NH_4NO_3}$ dissolves in water, it forms $\mathrm{NH_4^+}$ and $\mathrm{NO_3^-}$ ions, not $\mathrm{NH_3}$ or $\mathrm{NO_2^-}$.
