Why is color not always the best way to identify a mineral?
The reason for color not being the best way to identify a mineral.
Answer to Problem 7RQ
Color is not the best way to identify a mineral because the color of a mineral varies due to chemical impurities present in a mineral.
Explanation of Solution
Some minerals can be in many colors, or they can be colorless. The reason behind this is the chemical impurities that might be present in the minerals. If there are no impurities, then the mineral can be in its true color or be colorless. But if impurities are present, then same mineral can be in distinct colors.
The variety of color of a mineral will depend on the level of chemical impurity. For example, quartz is present in rose, milky white, and purple color. It can also be colorless if there are no impurities.
Conclusion:
Therefore, color is not the best way to identify a mineral because color of a mineral varies due to chemical impurities present in a mineral.
