ViviAluminium chloride is a powerful Lewis acid, capable of forming stable Lewis acid-base adducts with even weak Lewis bases such as benzophenone or mesitylene.[3] Not surprisingly it forms tetrachloroaluminate Al Cl4− in the presence of chloride ions.
In water, partial hydrolysis forms HCl gas or H3O+, as described in the overview above. Aqueous solutions behave similarly to other aluminum salts containing hydrated Al3+ ions, giving a gelatinous precipitate of aluminum hydroxide upon reaction with the correct quantity of aqueous sodium hydroxide: Al Cl3(aq) + 3 NaOH(aq) → Al(OH)3(s) + 3Na Cl(aq)
Chemical:
Aluminum is a highly reactive metal, although it does not appear to be. this is because as soon as the metal comes in contact with air it forms an oxide coating (AlO Aluminum oxide), this prevents it further reacting with oxygen or water. Like all metals aluminum also conducts electricity.
Physical:
Aluminum is a shiny metal making it visually appealing and it is also malleable.

Is the color of aluminum wire physical properties or chemical?
The color of aluminum wire is a physical property. It is determined by the way light interacts with the surface of the wire. This property can change based on external factors like oxidation or coatings, but it does not involve any chemical reactions.
Is the color of aluminum wire physical or chemical?
The color of aluminum wire is a physical property. It is determined by the way light is reflected off the surface of the metal without changing its chemical composition.
When we place aluminium foil into liquid bromine and find a white solid is that chemical or physical property?
That would be a chemical property, specifically a chemical reaction. The formation of a white solid (aluminum bromide) indicates a chemical change has occurred as the aluminum has reacted with the bromine to form a new substance.
Is the fact that a 1 inch cube of aluminum weighs less than a 1 inch cube of lead a physical or a chemical property?
This is a physical property because it is a characteristic that can be observed and measured without changing the substance's chemical composition. The difference in weight is explained by the different densities of aluminum and lead, which are inherent to the materials themselves.
Is color a chemical or a physical properties?
Color is a physical property, not a chemical property. It is determined by how an object interacts with and reflects light, rather than its chemical composition.
