What is the Difference Between Acidic and Basic Oxides?

The main difference between acidic and basic oxides lies in their reaction with water. Acidic oxides form acids when dissolved in water, while basic oxides form bases when dissolved in water.

Acidic Oxides:

• Formed when non-metals react with oxygen.
• Examples of acidic oxides include Cl2O, SO2, and P4O10.
• Found on the right side of the periodic table.

Basic Oxides:

• Formed when metals react with oxygen.
• Examples of basic oxides include Na2O, CaO, and MgO.
• Found on the left side of the periodic table.

Oxides can also be classified as amphoteric oxides, which can chemically react as either acidic or basic, or as neutral oxides, which do not exhibit acidic or basic properties.

Comparative Table: Acidic vs Basic Oxides

The main difference between acidic and basic oxides lies in their reaction with water. Here is a table summarizing the differences:

Acidic oxides, also known as acid anhydrides, react with water to form acids. For instance, sulfur dioxide (SO2) reacts with water to form sulfurous acid (H2SO3), while sulfur trioxide (SO3) reacts with water to form sulfuric acid (H2SO4). On the other hand, basic oxides react with water to form bases. For example, sodium oxide (Na2O) and magnesium oxide (MgO) react with water to form sodium hydroxide (NaOH) and magnesium hydroxide (Mg(OH)2), respectively.

There are also amphoteric oxides, which exhibit both acidic and basic properties, such as aluminum oxide (Al2O3). These oxides can react as either an acid or a base depending on the conditions and substances they interact with.
