Question

The basic strength of the oxides follows the order
a) Al2O3>MgO>Na2O
b)Al2O3<MgO<Na2O
c)Na2O3<MgO<Al3O2
d)Al2O3>MgO>Na2O​

Answer 1

Answer:

An oxide is that chemical compound which has a chemical formula containing at least one oxygen atom and one other element. Oxide is a dianion of oxygen. Oxides can be called as binary compounds formed by the reaction of oxygen with other elements. Oxides are classified as acidic, basic, neutral and amphoteric based on their characteristics.

Na2O, MgO, Al2O3, CuO is the decreasing order of basic nature.

Answer 2

Answer:

The basic strength of the oxides follows the order Al₂O₃<MgO<Na₂O.i.e.option(b).

Explanation:

• An oxide is a chemical compound with at least one oxygen atom and one additional element in its chemical formula.
• Oxide is an oxygen dianion.
• Oxides are binary chemicals that are created when oxygen reacts with other elements.
• Based on these properties, oxides are categorized as acidic, basic, neutral, and amphoteric.
• Acidic oxide:-They dissolve in water, and the resulting mixture exhibits acidic behavior. These oxides are referred to as anhydrides of acids as a result of this characteristic.
• Basic oxide:-They become dissolved in water and produce hydroxide ions, which are bases. The bases' anhydrides are called basic oxides.
• Amphoteric oxide:-These are oxides produced by elements whose properties cross over from the periodic table's metallic to non-metallic categories.

So, the basic strength of the oxides follows the order Al₂O₃<MgO<Na₂O.i.e.option(b).
