Question:
The chemical formula of Bauxite is
The chemical formula of Bauxite is
Show Hint
Bauxite is a hydrated oxide of aluminium and is represented as \(Al_2O_3\cdot 2H_2O\).
Updated On: May 7, 2026
- \(Al_2O_3\cdot H_2O\)
- \(Al_2O_3\cdot 3H_2O\)
- \(Al_2O_3\)
- \(Al_2O_3\cdot 2H_2O\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Bauxite is an important ore of aluminium. It is mainly a hydrated oxide of aluminium.
Step 1: Aluminium oxide is: \[ Al_2O_3 \]
Step 2: Bauxite is not pure anhydrous aluminium oxide. It contains water of hydration.
Step 3: The commonly represented formula of bauxite is: \[ Al_2O_3\cdot 2H_2O \]
Step 4: Since bauxite is a hydrated aluminium oxide, the correct formula among the given options is: \[ \boxed{Al_2O_3\cdot 2H_2O} \]
