Answer

Only FIRST statement regarding the extraction of aluminium using electrolysis is TRUE. The FALSE statement is that the extraction of ALUMINIUM using ELECTROLYSIS has a relatively low energy demand.

Explanation

## Step1: The EXTRACTION of ALUMINIUM USING ELECTROLYSIS is based on the principle that metal cations will attract the negatively charged electrode (cathode) where the cations will gain electrons and convert themselves to a neutral atom. Hence, the statement that "positively charged aluminum ions gain electrons from the cathode" is True. ## Step2: The main feature of the electrolysis of aluminum oxide is that it requires a lot of electrical energy. High temperatures (up to 1000 degrees Celsius) are needed to cause aluminum oxide to melt, which allows electrical conduction to separate the ion compounds. Therefore, saying "the process has a relatively low energy demand" is False. Electrolysis of aluminum is known for its high energy consumption.
