Aluminium oxide is able to
|
|
neutralise potassium hydroxide solution to form a colourlesssolution
|
|
|
neutralise dilute sulphuric acid to form a colourlesssolution
|
|
|
dissolve in water to release hydrogen ions
|
|
|
melt at a low temperature
|
Explanation:
Detailed explanation-1: -Aluminium reacts with sulphuric acid to form Aluminium sulphate.
Detailed explanation-2: -Reaction with acids: Aluminum oxide contains oxide ions, and thus reacts with acids in the same way sodium or magnesium oxides do. Aluminum oxide reacts with hot dilute hydrochloric acid to give aluminum chloride solution. This reaction and others display the amphoteric nature of aluminum oxide.
Detailed explanation-3: -aluminium reacts with sulfuric acid to produce aluminium sulfate and hydrogen gas according to the following equation: H2SO4 (aq) + Al (s) = Al2 (SO4)3 (aq) + H2 (g).
