The valency of iron in hematite is ............
Show Hint
Correct Answer: 3
Solution and Explanation
Step 1: Understanding hematite.
Hematite is an iron oxide mineral with the chemical formula Fe₂O₃. The iron in hematite exists in the +3 oxidation state (Fe³⁺).
Step 2: Conclusion.
The valency of iron in hematite is 3.
