**Question:**

Write a balanced ionic equation for the reaction of Fe²⁺, Fe³⁺, and OH⁻ to form magnetite, Fe₃O₄(s). H₂O may enter into the equation.

**Explanation:**

This question prompts the formulation of a balanced ionic equation for the reaction between ferrous ions (Fe²⁺), ferric ions (Fe³⁺), and hydroxide ions (OH⁻) that results in the formation of magnetite (Fe₃O₄) as a solid precipitate. Water (H₂O) may be involved in balancing the equation. 

To balance the ionic equation, follow these steps:

1. Write the unbalanced equation:
   \[
   \text{Fe}^{2+} + \text{Fe}^{3+} + \text{OH}^- \rightarrow \text{Fe}_3\text{O}_4(s)
   \]

2. Determine the required proportions of reactants to produce Fe₃O₄ while maintaining charge and mass balance.

3. Balance both the atoms and charges on each side of the equation.

4. Consider including water if necessary to balance oxygen and hydrogen atoms.

By providing this educational content on the website, students will learn about balancing ionic equations, the specific reaction presented, and the formation of magnetite.
