Q. Assertion :

M g O

is reduced by

S i

whereas

S i O_{2}

can be reduced by

M g

Reason:

S i

reduces

M g O

at high temperature

M g

is more electropositive than

S i

and thus reduces

S i O_{2}

Si of high purity to be used in semiconductor can be prepared by following methods :

I. $S i O_{2} + 2 C \to S i + 2 C O$

II. $S i + 2 C l_{2} \to S i C l_{4}$

$S i C l_{4} + 2 M g \to S i + 2 M g C l_{2}$

Better method is :

S i O_{2} + 3 C ⟶ 2 C O +
