Answer:

$\boxed {&#10029\red{Answer~}&#10029}$

In the metallurgy of aluminium, the metal is to be isolated from alumina (Al2O3) by carrying out its electrolytic reduction. The melting point of alumina very high (2323 K).

Answer 2

Answer:

Q.what is the role of cryolite in metallurgy of aluminium ?

Explanation:

In the metallurgy of aluminium, the metal is to be isolated from alumina (AI203) by carrying out its electricity reduction. The melting point alumina very high

(2323k). It is therefore, mixed with cryolite (Na3AIF6).which lowers it's melting point to 1173 k. Moreover, cryolite also increase the electrical conductivity of alumina ..
