In the lake tast for `Al^(3+)` ions, there is the formation of coloured 'floating lake'. It is due to :

A

Adsorption of litums by `[Al(OH)_(4)]^(-)`

B

Adsorption of litums by `Al(OH)_(3)`

C

Adsorption of litums by `H_(2)O`

D

None of the above.

Text Solution

Verified by Experts

The correct Answer is:
B
In the Lake test of `Al^(3+)` ions, the gelatineous white precipitate of `Al(OH)_(3)` has the capacity to adsorb blue litums (a day). As a result, a blue lake is formed that floats over colourless solution.
