Assertion: Al(OH)(3) is insoluble in NH(...

Assertion: `Al(OH)_(3)` is insoluble in `NH_(4)OH` but soluble in `NaOH`.
Reason: `NaOH` is a stronger base.

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
It is true that `Al(OH)_(3)` is soluble in NaOH . The reason is that NaOH is a strong alkali, it dissolves `Al(OH)_(3)` . Which is amphoteric in nature and forms `NaAlO_(2)`
`Al(OH)_(3) + NaOH rarr underset("Sodium meta aluminate")(NaAlO_(2)) + 2H_(2)O`
