Question

(a) Name the metal which is extracted from haematite ore.
(b) Name one ore of aluminium. Name the aluminium compound present in this ore and write its chemical formula.
(c) How is aluminium metal extracted? Explain with the help of an equation.
(d) Name the electrode at which aluminium metal is produced.
(e) Which gas is produced during the extraction of aluminium? At which electrode is this gas produced?

Answer 1

Answer:(a)-Iron metal

(b)-Al2O3.nH2O

(c)- Aluminium metal is extracted by electrolytic extraction of alumina.

(d)- Aluminium metal is released at cathode

(e)- Oxygen gas is liberated at anode.

Explanation:

Answer 2

(a). Iron ( Fe ) is extracted from hematite ore. It's formula is Fe$_{2}$O$_{3}$ .

(b). Bauxite is one of the ores of Aluminium . The aluminium compound is Aluminium hydroxide. It's chemical formula is Al$_{2}$O$_{3}$ . nH$_{2}$O .

(c). Aluminium is exerted through electrolysis from its ore.

   Al$_{2}$O$_{3}$ ---------> 2$Al^{+3}$ + 3$O^{2-}$

(d). Aluminium metal is produced at cathode .

(e). Oxygen is produced during the extraction of aluminium . It is produced at anode .
