Question

How to separate mixture of Al(OH)3 and Fe(OH)3​

Answer 1

Answer:

Given,

A mixture of $\bold\red{Al{(OH)}_{3}}$ and $\bold\red{Fe{(OH)}_{3}}$.

Now,

we need to separate the compounds.

Steps for Separation are :-

• It can be easily separated by the use of concentrated NaOH Solution.

• The NaOH Solution react only with $Al{(OH)}_{3}$ and forms soluble aluminate.

• $Fe{(OH)}_{3}$ will remain in the residue.

Now,

The balanced equation for the reaction is :-

$Al{(OH)}_{3}+NaOH->NaAlO_{2}+2H_{2}O$
