Question

Write the net ionic equation to show the formation of a precipitate (insoluble salt) when the following solutions are mixed. Write noreaction if there is no precipitate.

FeCl3(aq) and NH4(NO)3(aq)
Express your answer as a chemical equation. Identify all of the phases in your answer. Enter noreaction if no precipitate is formed.

Answer 1

Let's first write the chemical dissociation processes:
FeCl₃(aq) = Fe₃⁺(aq) + 3Cl^-(aq)
NH₄(NO)₃(aq) = NH₄⁺(aq) + 3NO₃^-(aq)
When solutions are mixed no precipitate formed, due to the solubility of all the reaction products. So there's no chemical reaction between them, because Fe(NO₃)₃ and NH₄Cl are soluble.
