the main compound of aluminum and chlorine. It is white, but samples are often contaminated with iron trichloride, giving it a yellow colour. The solid has a low melting and boiling point. It is mainly produced and consumed in the production of aluminum metal, but large amounts are also used in other areas of chemical industry. The compound is often cited as a Lewis acid. It is an example of an inorganic compound that "cracks" at mild temperature, reversibly changing from a polymer to a molecule.
When heated, aluminium hydroxide undergoes dehydration and transforms into alumina (aluminum oxide). This process occurs at around 300-400°C, depending on the specific form of aluminium hydroxide being heated.
2Al + 3Cl2 ---> 2AlCl3
Aluminum + Chlorine ---> Aluminum chloride

What is the Product of aluminium hydroxide oxalic acid and potassium oxalate?
The product of aluminium hydroxide and oxalic acid is aluminium oxalate, while the product of aluminium oxalate and potassium oxalate is potassium oxalate and aluminium oxalate.
What happens to the sodium and hydroxide ions after electrolysis?
The sodium ions combine with water molecules to form sodium hydroxide, while the hydroxide ions combine with hydrogen ions to form water. This process results in the production of sodium hydroxide and hydrogen gas.
How is aluminium extracted?
Aluminium is extracted from its ore, bauxite, using the Bayer process. This involves crushing the bauxite, dissolving it in hot sodium hydroxide solution to form aluminate solution, then cooling and filtering it to separate out impurities. The alumina is then electrolyzed to produce aluminium metal.
What happens when iron oxide is added to sodium hydroxide solution?
When iron oxide is added to sodium hydroxide solution, a reaction occurs to form iron(III) hydroxide and water. The iron(III) hydroxide will appear as a brownish precipitate in the solution, while water remains as a liquid.
How is ammonia different from sodium hydroxide?
Ammonia is a compound that contains nitrogen and hydrogen, while sodium hydroxide is a compound made up of sodium, oxygen, and hydrogen. Ammonia is a weak base, while sodium hydroxide is a strong base. Additionally, ammonia is a gas at room temperature, while sodium hydroxide is a solid.
What is the Product of aluminium hydroxide oxalic acid and potassium oxalate?
The product of aluminium hydroxide and oxalic acid is aluminium oxalate, while the product of aluminium oxalate and potassium oxalate is potassium oxalate and aluminium oxalate.
When copper ii hydroxide and sodium nitrate is heated?
When copper II hydroxide and sodium nitrate are heated together, they may undergo a decomposition reaction. Copper II hydroxide will decompose into copper II oxide and water, while sodium nitrate will decompose into sodium nitrite and oxygen.
What happens to the sodium and hydroxide ions after electrolysis?
The sodium ions combine with water molecules to form sodium hydroxide, while the hydroxide ions combine with hydrogen ions to form water. This process results in the production of sodium hydroxide and hydrogen gas.

The alumina is then electrolyzed to produce aluminium metal.
What are the ingredients in mylanta?
The active ingredients in Mylanta are aluminum hydroxide, magnesium hydroxide, and simethicone. Aluminum and magnesium hydroxide work as antacids to neutralize stomach acid, while simethicone helps reduce gas in the stomach and intestines.
What happens when iron oxide is added to sodium hydroxide solution?
When iron oxide is added to sodium hydroxide solution, a reaction occurs to form iron(III) hydroxide and water. The iron(III) hydroxide will appear as a brownish precipitate in the solution, while water remains as a liquid.
What happens when Zinc sulfate reacts with potassium hydroxide?
When zinc sulfate reacts with potassium hydroxide, zinc hydroxide is formed as a white precipitate, while potassium sulfate remains in solution. This reaction is a double displacement reaction where the cations and anions of the two compounds switch partners.
What happens when aluminum sulfate reacts with strontium hydroxide?
When aluminum sulfate reacts with strontium hydroxide, aluminum hydroxide and strontium sulfate are formed as products in a double displacement reaction. Aluminum hydroxide is insoluble in water and will precipitate out of the solution, while strontium sulfate will also be a precipitate since it is insoluble in water.
What expands quicker aluminium or aluminium bronze?
Aluminium bronze expands at a quicker rate than aluminium due to its higher thermal expansion coefficient. Aluminium bronze is a copper-based alloy that contains aluminium, which makes it expand more with heat compared to pure aluminium.
What name is used for the main type of thermal energy transfer that happens when a gas is heated?
The main type of thermal energy transfer that happens when a gas is heated is convection. In convection, the heated gas molecules become less dense and rise, while cooler gas molecules sink, creating a circular motion that transfers heat throughout the gas.
Who has more hydrogen atoms hydroxide or acetate?
Hydroxide is OH. Acetate is C2H3O2. So Acetate has three while Hydroxide has one.
Solid sodium hydroxide Decomposes into gaseous water and solid sodium oxide?
Solid sodium hydroxide will decompose into gaseous water and solid sodium oxide when heated to high temperatures. This decomposition reaction is a result of the breakdown of sodium hydroxide into its constituent elements due to the input of energy. Water vapor is released while sodium oxide remains as a solid residue.
