Question

is this equation is the extraction of aluminium from cryolite? ​

Answer 1

Answer:

no it is extraction of aluminum from bauxite ore

Answer 2

Answer:

The given reaction is,

⇒ Extraction of Aluminium Oxide from Bauxite.

Explanation:

The given reaction is extraction of Aluminium Oxide from Bauxite by, heating Bauxite , to remove water of Crystalisation.

⇒ $Al_2O_3.2H_2O + Heat \rightarrow Al_2O_3(s) + 2H_2O(g) \uparrow$

 (Bauxite)  + (Heat)  →  (Aluminium Oxide) + (Water of Crystalisation) (removed from it's molecule - Bauxite)

__

Extraction of Aluminium from Cryolite is done by electrolysis of Aluminium Oxide (in mixture of Cryolite),. Not by heating Aluminium Oxide dihydrate.

Cryolite chemical formula : $Na_3AlF_6$
