Red bauxite contains chief impurity of ferric oxide but contains some amount of `SiO_(2)` is subjected to Baeyer'sprocess then select correct reason for `SIO_(2)`.

A

`SiO_(2)`remains unaffected by reagent of Baeye's process

B

`FeSiO_(3)`slag is formed by the reaction of `SiO_(2)`and ferric oxide

C

`SiO_(2)`is decomposed to produced elementaol `Si`and `O_(2)` gas which removed in the from of vapour

D

`SiO_(2)`dissolves in the from of silicate ion

Text Solution

Verified by Experts

The correct Answer is:
D
`underset("Aci dic")(SiO_(2))+underset("Basic")(2NaOH) rarrunderset("Solub l esiicate")(Na_(2)SiO_(3)) +H_(2)O`
