Answer:

i think al2o3 ....................

Answer 2

Answer:

Sulphur dioxide is an acidic oxide

Explanation:

Acidic oxides -SO2,CO2 .

• Sulphur dioxide is an acidic gas and this can easily be demonstrated by adding water and a few drops of universal indicator to a container of the gas. The resulting acid is the weakly dibasic acid sulphurous acid (H2SO3).
• The property of carbon dioxide to behave like an acid and react with an alkali makes it an acidic oxide. Acidic oxides are a type of oxides that react with alkalis to form salt and water.

Basic oxides -Na2O, MgO

• Magnesium oxide is a simple basic oxide, because it contains oxide ions. It reacts with water to form magnesium hydroxide which is a base Aluminium oxide is amphoteric. It has reactions as both a base and an acid.
• Acidic oxides are oxides of non-metals and basic oxides are oxides of metals
• As sodium is a metal so; so its oxide Na2O will be basic in nature. So Na2O is basic oxide, when it mixes in water it will give NaOH which is a base
