Bauxide ore is made up of `Al_(2)O_(3) + SiO_(2) + TiO_(2) + Fe_(2) O_(3)`. This ore is treated with conc. `NaOH` solution at `500 K` and `35` bar pressure for a few hours and filtered hot. In the filtrate, the species present are

A

`NaAl(OH)_(4)` only

B

`Na_(2)Ti(OH)_(6)` only

C

`NaAl(OH)_(4)` and `Na_(2)SiO_(3)` both

D

`Na_(2)SiO_(3)` only

Text Solution

Verified by Experts

The correct Answer is:
C
`Al_(2)O_(3)` and `SiO_(2)` reacts with conc. `NaOH` to give `NaAl(OH)_(4)` and `Na_(2)SiO_(3)` respectively.
