Question:
Formula of chromium ore?
Formula of chromium ore?
Show Hint
When identifying ores, remember that the most common ores of a metal are usually oxides or sulfides. Chromium ore is most commonly found as \( \text{Cr}_2\text{O}_3 \).

- \( \text{Cr}_2\text{O}_3 \)
- \( \text{Cr}_2\text{O}_4 \)
- \( \text{CrO}_2 \)
- \( \text{Cr}_3\text{O}_4 \)
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The most common chromium ore is \( \text{Cr}_2\text{O}_3 \), also known as chromium(III) oxide. It is the primary source of chromium for industrial purposes. Other chromium compounds, such as \( \text{Cr}_2\text{O}_4 \) and \( \text{CrO}_2 \), exist but are not as commonly used as ores for chromium extraction.
Thus, the correct answer is \( \text{Cr_2\text{O}_3} \).
Thus, the correct answer is \( \text{Cr_2\text{O}_3} \).
