Question:
The percentage of Cr(III) in Ruby is
The percentage of Cr(III) in Ruby is
Show Hint
Chromium (Cr) is the element responsible for the red color in ruby, with its content typically ranging from 0.5% to 1\%.
Updated On: Apr 30, 2025
- 0.5 to 1 \%
- 1 to 2 \%
- 0.1 to 0.4 \%
- 2 to 3 \%
- 0.1 to 0.3 \%
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Ruby is a gemstone composed of corundum (Al₂O₃), where small amounts of chromium (Cr) are incorporated into the crystal lattice, giving the gemstone its characteristic red color.
- The percentage of chromium in ruby is typically between 0.5\% and 1\% by weight. The chromium atoms are responsible for the red color due to the absorption of certain wavelengths of light.
Thus, the correct answer is (A) 0.5 to 1 \%.
