NaOH can be used to seprate Al(OH)(3) ...

`NaOH` can be used to seprate `Al(OH)_(3) `and `Zn(OH)_(2)` . (T/F)

Text Solution

Verified by Experts

The correct Answer is:
F
`NaOH` can dissolve both `AI(OH)_(2)` and `Zn(OH)_(2)`
`AI(OH)_(3) + NaOH rarr NaAIO_(2) `or `Na[AI(OH)_(6)]+ 2H_(2)O`
`Zn(OH)_(2) + 2NaOH rarr Na_(2)(Zn(OH)_(4)] or Na_(2)ZnO_(2) + 2H_(2)O`
