Which sequence describes the process accurately?

A. I, II, III, IV

B. I, II, IV, III

C. IV, III, II, I

D. III, V, IV

Answer 1

The correct sequence for the described process is I, II, IV, III. Lions and Olons are not relevant to this question.

Step-by-step explanation:

The correct sequence that describes the process accurately is B. I, II, IV, III.

Lions and Olons are not relevant to this question. The given statements describe the steps of the electrolysis process used for the extraction of aluminum.

First, in step I, AP ions (meaning aluminum ions) are attracted to the negative electrode (cathode) at the bottom, while O₂ ions (meaning oxygen ions) are attracted to the positive electrode (anode) at the top.

Then, in step II, electric current is added to the setup, and electrolysis begins.

In step IV, bauxite (an aluminum ore) is added to molten cryolite in a tank with graphite electrodes.

Finally, in step III, oxygen and carbon from the graphite anode react to form carbon dioxide, while pure aluminum from the aluminum ions at the cathode is collected.
