Borax bead test is not suitable of for `Al(III)`
`Al_(2)O_(3)` is insoluble in `H_(2)O`.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
B
Borax bead test is not suitable for Al(III) because its oxidising as well as reducing flame is clourless in both hot as well as cold. Alumina is insoluble in water as they exist in hydrated from like `Al_(2)O_(3) cdot 2H_(2)O, Al_(2)O_(3) cdot H_(2)O` etc.
