This is the exception: Al(OH)3 is not made of ions, it is a substance made of molecules, and it should not be confused with AlCl3, which is an ionic compound.
Aluminium hydroxide genusAmphoteric hydroxides。Due to its presence in two ionized forms, it is both a weak acid.
It can have the acid chemical formula H3alo3, which is a weak base, and can have the basic chemical formula Al(OH)3. Aluminum hydroxide is amphoteric and can react with both acids and bases.
Introduction] Aluminum hydroxide, chemical formula Al(OH)3, is the hydroxide of aluminum. Aluminum hydroxide can react with acids to form salts and water and strong bases to form salts and water, so it is also an amphoteric hydroxide. The chemical formula Al(OH)3 is a hydroxide of aluminum.
Because it is acidic, it can also be called aluminic acid (H3alo3). However, when it actually reacts with a base, it forms tetrahydroxyaluminate ([Al(OH)4]-), so it is usually regarded as metaaluminic acid monohydrate.

Anonymous users2024-02-12Aluminium hydroxide is an amphoteric hydroxide that reacts with both strong acids and strong bases.
Reaction with strong acids:
al(oh)3+3hcl → alcl3+3h2o
Reaction with a strong base:
al(oh)3+naoh → na[al(oh)4]
Two ionizations in aluminium hydroxide water:
1. Al(OH)3 Al3+ +3OH- (basic ionization).
2. Al(OH)3 + H2O Al(OH)4]- H+ (acid ionization).

Anonymous users2024-02-11Aluminum hydroxide is an inorganic substance with the chemical formula Al(OH) and is the hydroxide of aluminum.
The lead limb formula Al(OH)3 of aluminum hydroxide is the hydroxide of aluminum. Aluminum hydroxide can react with acids to form salts and water as well as strong bases to form salts and water, so it is an amphoteric hydroxide. Because it is acidic, it can also be called aluminic acid (H3alo3).
However, when it actually reacts with a base, it is tetrahydroxyaluminate ([Al(OH)4]-), so it is usually regarded as metaaluminic acid monohydrate (halo2·H2O), which is divided into two types: industrial grade and pharmaceutical grade according to its use.

Anonymous users2024-02-09Answer: Aluminium oxide is an inorganic substance, the chemical formula Al2O3, is a high hardness compound, melting point of 2054, boiling point of 2980, ionic crystals that can be ionized at high temperatures, often used in the manufacture of refractory materials.
Industrial alumina is prepared from bauxite (Al2O3·3H2O) and diaspore, and Al2O3 with high purity requirements is generally prepared by chemical methods.
Al2O3 has many homogeneous crystals, more than 10 kinds of which are known, and there are mainly 3 crystal forms, namely -Al2O3, -Al2O3, and -Al2O3. Among them, the structure is different and the properties are also different, and it is almost completely converted to -Al2O3 at high temperatures above 1300.
It doesn't belong. Bleaching refers to the ability to discolor colored organics (e.g. litmus, phenolphthalein, etc.).

In my opinion, although calcium carbonate is a precipitation, according to the ionization equilibrium constant, it will dissolve a very small part in water, but the part it dissolves is completely ionized into calcium ions and carbonate in water, so it is a strong electrolyte The same is true for aluminum hydroxide, aluminum hydroxide will also ionize, but not completely, aluminum ions will hydrolyze and form aluminum hydroxide, so it is a weak electrolyte.
It's not precipitation, it's colloidal, upstairs, did you study chemistry in high school, there are three states of substance in the liquid, dissolve into it, precipitate, and there is one in between, colloid, it neither precipitates nor dissolves, like iron hydroxide, aluminum hydroxide are colloids. >>>More
