Is aluminum hydroxide basic

Answer 1

Only free, dissolved hydroxides of alkali and earth alkali metals are strong because (OH-)aq is a strong base only if it is a free ion in water.

Iron is a (polyvalent) transition metal of which the hydroxides are (partially) non-dissolvable and can form mixed hydrate complex ions (e.g. Fe(OH)3(H2O) ).

It is both a weak base and a weak acid!! (all reactions are equilibrium reactions of protolysis)

• basic:

  Fe(OH)3(H2O) + H3O+ <=> Fe+(OH)2(H2O)2 + H2O

  or

  Fe(OH)3(H2O) + H2O <=> Fe+(OH)2(H2O)2 + OH-

• acidic:

  Fe(OH)3(H2O) + OH- <=> Fe(OH)4- + H2O

  or

  Fe(OH)3(H2O) + H2O <=> Fe(OH)4-+ H3O+

Answer 2

Aluminium hydroxide is a base. all hydroxides are bases

Answer 3

It is not a weak base, it is a strong/powerful base. It is also known as Lye.

Answer 4

I believe it is a weak base as the only strong bases are the hydroxides of the alkali metals and the heavy alkaline earths(Sr, Ba, & Ca).

Answer 5

No, like the other alkali metal hydroxides, it is a strong base.

Answer 6

No. It is a weak base as it has a very low solubility.

Answer 7

Lead hydroxide is a weak base. The strong bases are the alkali metal and alkaline earth metal hydroxides.

Answer 8

Yes. Aluminium hydroxide is a base. It ionises to produce hydroxide ions.

Answer 9

yes, it is
