Iron III Oxide and Water Interactions

The video explores the interaction between iron III oxide (Fe2O3) and water. Iron III oxide is a solid, and water is a liquid. The video explains that iron III oxide is an ionic compound, typically insoluble in water. A solubility table is used to confirm that iron III oxide does not dissolve in water. The conclusion is that when iron III oxide is placed in water, it remains a solid and does not react or dissolve.
