Question

Why is Alumina dissolved in molten cryolite for electrolysis to obtain aluminium metal

Answer 1

HII #DEAR ❤❤❤❤❤❤


⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️

ALUMINIUM HAS VERY HIGH MELTING PØINT..

(over 2,000°C),

so it would be expensive to melt it. Instead, it is

dissolved in molten cryolite, 



SO Alumina DISSOLVED IN MØLTEN CRYOLITE.


HOPE IT HELPS U....!!

• Aluminium oxide has a very high melting point (over 2000oC) so it would be expensive to melt it. So it is dissolved in molten cryolite -which has a lower melting point than aluminium oxide. The use of cryolite reduces some of the energy costs involved in extracting aluminium.
