In this lesson, we will learn how to describe the extraction of aluminum from its ore using electrolysis.
Q1:
Aluminum is commonly extracted by electrolysis of aluminum oxide (AlO)23. Before it can be electrolyzed, the aluminum oxide must be molten. However, aluminum oxide has a melting point of over 2,000∘C, which is very expensive to maintain. What is added to lower the melting point of the aluminum oxide before electrolysis?
Q2:
Which of the following is an ore of aluminum?
Q3:
What is the chemical compound of aluminum found in the greatest percentage in the ore used in the extraction process?
