Question

Which is the correct net ionic equation for the reaction of aqueous ammonia with nitric acid? Which is the correct net ionic equation for the reaction of aqueous ammonia with nitric acid?NH3(aq) + NO3−(aq) → NH2−(aq) + HNO3(aq)NH4+(aq) + H+(aq) → NH52+(aq)NH2−(aq) + H+(aq) → NH3(aq)NH4+(aq) + NO3−(aq) → NH4NO3(aq)NH3(aq) + H+(aq) → NH4+(aq)

Answer 1

Answer:

The last option:

• NH₃ (aq) +  H⁺ (aq)  →  NH₄⁺ (aq)

Explanation:

1) Word equation

• Aqueous ammonia + nitric acid → aqueous ammonium nitrate

2) Chemical (molecular) equation

• NH₃ (aq) + HNO₃ (aq)  → NH₄ NO₃

3) Ionization reactions

Write the dissociation of the soluble ionic compounds:

• HNO₃ → H⁺ + NO₃⁻

• NH₄ NO₃ → NH₄⁺ + NO₃⁻

4) Total ionic equation:

• NH₃ (aq) +  H⁺ (aq) + NO₃⁻ (aq) →  NH₄⁺ (aq) + NO₃⁻ (aq)

5) Net ionic equation

You must cancel the spectator ions, which are those ions that are repeated in both reactant and product sides, i.e. NO₃⁻. They are name spectator because they do not participate (change) during the reaction.

• NH₃ (aq) +  H⁺ (aq)  →  NH₄⁺ (aq)

And that is the last choice of the list.
