Question
Chapter 21, Problem 21.41QP
Interpretation Introduction
Interpretation:
The Hall process for preparation of aluminum has to be described.
Concept introduction:
Hall process:
Electrolysis is the key process involved in Hall process.- The smelting or separation of aluminum from its ores is done by Hall process. This is the major industrial method for smelting of aluminum.
- Elemental aluminum is not produced by doing electrolysis of an aqueous aluminum, why because hydronium ion easily oxidize the elemental aluminum.
- So, we use molten aluminum salt as raw material for the electrolysis process in Hall process.
