A mixture of `Al_(2)O_(3) and Fe_(2)O_(3)` can be separated by using

A

Sodium hydroxide

B

Cold water

C

Ethyl alcohol

D

Boling wate

Text Solution

Verified by Experts

The correct Answer is:
A
NaOH is the leaching reagent which is used to separate `Al_(2)O_(3) and Fe_(2)O_(3)`from the mixture. NaOH dissolves `Al_(2)O_(3)` but not `Fe_(2)O_(3)`.
