Final answer:
The reaction between NaOH and FeCl₃ leads to the formation of a soluble salt (NaCl) and an insoluble hydroxide (Fe(OH)3). The complete ionic and net ionic equations reflect the dissolution of reactants into ions and the formation of the insoluble precipitate, with Na⁺ and NO₃⁻ as spectator ions.
Step-by-step explanation:
The reaction between NaOH and FeCl₃ involves a double-replacement reaction, leading to the formation of NaCl, which is a soluble salt, and Fe(OH)₂ or Fe(OH)₃, which is an insoluble hydroxide precipitate. The complete ionic equation breaks down all soluble reactants and products into their constituent ions, while the net ionic equation shows only those ions that directly participate in the reaction. As a result, the net ionic equation would illustrate the formation of the insoluble Fe(OH)3 precipitate from Fe³⁺ ions and OH⁻ ions. Spectator ions, such as Na⁺ and Cl⁻ or NO₃⁻, do not participate in forming the precipitate and are not included in the net ionic equation.
Based on the information given and solubility rules, when NaOH is mixed with FeCl₃, a reaction occurs, leading to the visual observation of a rusty red precipitate (Fe(OH)₃), indicating the formation of an insoluble substance. This observation serves as evidence of the reaction.
