How is the theory of complexes used to sperate `Fe_2O_3` and `Al_2O_3` ?

Text Solution

Verified by Experts

`Al_(2)O_(3)` is separated from `Fe_(2)O_(3)` using aqueous caustic soda. `Al_(2)O_(3)` acts as acid to `NaOH` and forms a soluble complex. `Fe_(2)O_(3)` acts as a base and is insoluble, which is separated by filtration.
`Al_(2)O_(3)+NaOH rarr Na[Al(OH)_(4)(H_(2)O)_(2)]`.
