- \(FeCrO_4\)
- \(FeCr_2O_3\)
- \(Cr_2O_4\)
- \(FeCr_2O_4\)
- \(Fe_2Cr_2O_4\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Chromite is the principal ore of chromium.
Step 2: Detailed Explanation:
Chromite ore has the formula \(FeCr_2O_4\) (Iron(II) chromate(III)). It contains Fe\(^{2+}\) and Cr\(^{3+}\) ions. It is also written as FeO·Cr\(_2\)O\(_3\).
Step 3: Final Answer:
Chromite ore is \(FeCr_2O_4\).
Chromite is the principal ore of chromium.
