Non-Metallic Oxides and Bases

When non-metallic oxides react with bases, they form salt and water as the products. This chemical reaction is known as acid-base neutralization reaction. Non-metallic oxides are acidic in nature and when they react with bases, they neutralize the basic properties of the base.

Examples of Non-Metallic Oxides

Some common examples of non-metallic oxides include carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen dioxide (NO2), and phosphorus pentoxide (P2O5). These oxides dissolve in water to form acidic solutions, which have a pH less than 7.

Reaction between Non-Metallic Oxides and Bases

The reaction between non-metallic oxides and bases can be represented by the following general equation:

Non-Metallic Oxide + Base → Salt + Water

For example, when carbon dioxide reacts with sodium hydroxide (NaOH), the following reaction takes place:

CO2 + 2NaOH → Na2CO3 + H2O

In this reaction, carbon dioxide reacts with sodium hydroxide to form sodium carbonate and water.

Similarly, when sulfur dioxide reacts with calcium hydroxide (Ca(OH)2), the following reaction takes place:

SO2 + Ca(OH)2 → CaSO3 + H2O

In this reaction, sulfur dioxide reacts with calcium hydroxide to form calcium sulfite and water.

Conclusion

In conclusion, the reaction between non-metallic oxides and bases is an acid-base neutralization reaction, which results in the formation of salt and water. Non-metallic oxides are acidic in nature and when they react with bases, they neutralize the basic properties of the base. The products of the reaction depend on the specific non-metallic oxide and base involved in the reaction.

The oxides of nan metals are acidic in nature. For example, CO2 nd SO2 are acidic in nature. Bases react with acidic oxides to form salt nd water. E.g. 2NaOH + CO2----> Na2Co3+H2OCa(OH)2 + SO2----> CaSO3+H2OIn general, Base+Nonmetallic oxide------> Salt+Water.
