Assertion : Na(2)ZnO(2) is water soluble...

Assertion : `Na_(2)ZnO_(2)` is water soluble whereas `Zn(OH)_(2)` is insoluble.
Reason : Addition of `NaOH` solution to `ZnCl_(2)` gives white ppt. which dissolves on further addition of `NaOH` due to the formation of complex cation.

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 assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
c

`ZnCl_(2)+2NaOH rarr Zn(OH)_(2)+2NaCl`
`Zn(OH)_(2)+2NaOH rarr Na_(2)[ZnO_(2)]+2H_(2)O`
`[Zn_(2)O]^(2-)` is a complex anion.
