The chemical reaction between iron(III) oxide (Fe₂O₃) and hydrochloric acid (HCl) can be represented as follows:
\[ \text{Fe}_2\text{O}_3 + 6 \text{HCl} \rightarrow 2 \text{FeCl}_3 + 3 \text{H}_2\text{O} \]
Note that Fe₂O₅ is not a common oxidation state for iron; it often exists as Fe₂O₃. If you meant iron(II) oxide (FeO) or were referencing a particular context where Fe₂O₅ is indeed relevant, please provide more details, and I can assist you further.
If you indeed meant Fe₂O₅ and it reacts with HCl:
\[ \text{Fe}_2\text{O}_5 + 10 \text{HCl} \rightarrow 2 \text{FeCl}_3 + 5 \text{H}_2\text{O} \]
This equation shows the reaction of iron(III) oxide with hydrochloric acid, producing iron(III) chloride and water.
