When metallic oxides react with acid they form salt and water soo they r basic in nature.....

》In the same way when non metalic oxides react with bases then they form salt and water soo they r acidic in nature


Acid +base--->Salt +water

Metallic Oxides - Basic Nature

Metallic oxides are compounds formed by the combination of a metal element with oxygen. These oxides typically exhibit basic properties when dissolved in water or when they react with an acidic substance. The basic nature of metallic oxides can be explained by considering the behavior of metal cations and the hydroxide ion (OH-) in solution.

1. Formation of Metal Cations:
- Metals tend to lose electrons to form cations.
- When a metal reacts with oxygen, it loses electrons and forms a metal cation.
- For example, in the reaction between sodium (Na) and oxygen (O2), sodium oxide (Na2O) is formed, and sodium loses electrons to form Na+ cations.

2. Reaction with Water:
- When a metallic oxide is dissolved in water, it undergoes hydrolysis.
- The oxide ion (O2-) reacts with water to form hydroxide ions (OH-).
- For example, when sodium oxide (Na2O) is dissolved in water, it reacts with water to form sodium hydroxide (NaOH).

3. Basic Properties:
- The presence of hydroxide ions (OH-) in the solution gives it basic properties.
- Hydroxide ions can accept protons (H+) from an acidic substance, thereby neutralizing the acidity.
- This ability to neutralize acids is the characteristic property of bases.
- When a metallic oxide reacts with an acid, the hydroxide ions combine with the hydrogen ions (H+) from the acid to form water.

Non-Metallic Oxides - Acidic Nature

Non-metallic oxides are compounds formed by the combination of a non-metal element with oxygen. These oxides typically exhibit acidic properties when dissolved in water or when they react with a basic substance. The acidic nature of non-metallic oxides can be explained by considering the behavior of non-metallic elements and the hydronium ion (H3O+) in solution.

1. Formation of Non-Metallic Oxides:
- Non-metals tend to gain electrons to form anions.
- When a non-metal reacts with oxygen, it gains electrons and forms a non-metallic oxide.
- For example, in the reaction between sulfur (S) and oxygen (O2), sulfur dioxide (SO2) is formed, and sulfur gains electrons to form SO2- anions.

2. Reaction with Water:
- When a non-metallic oxide is dissolved in water, it undergoes hydrolysis.
- The oxide anion (O2-) reacts with water to form hydronium ions (H3O+).
- For example, when sulfur dioxide (SO2) is dissolved in water, it reacts with water to form sulfurous acid (H2SO3).

3. Acidic Properties:
- The presence of hydronium ions (H3O+) in the solution gives it acidic properties.
- Hydronium ions can donate protons (H+) to a basic substance, thereby neutralizing the basicity.
- This ability to neutralize bases is the characteristic property of acids.
- When a non-metallic oxide reacts with a base, the hydronium ions combine with the hydroxide ions (OH-) from the base to form water.

In summary, metallic oxides are basic in nature
