What is the reaction of a non-metallic oxide with the base?

By Ritesh|Updated : November 9th, 2022

When non-metal combines with oxygen gas, non-metallic oxides are created. An oxide that is not metallic has an acidic character. Carbon dioxide is an example of a non-metallic oxide. Non-metallic oxide is formed generally through the following reaction:

Non-metal + Oxygen → Non-metallic oxide

It is demonstrated that non-metallic oxides are acidic in nature when they react with bases to produce the corresponding salt and water.

The reaction of nonmetal oxide with base:

CO2 + 2NaOH → Na2CO3 + H2O

What is a base?

When dissolved in aqueous fluids, a chemical is said to be a "base" in chemistry if it releases hydroxide ions. Basic compounds are typically slippery to the touch and have a harsh taste (particularly alkalis). Additional salient features of bases include:

  • They convert the red litmus paper's color to blue.
  • Salts are created by chemical interactions between them and acidic substances.
  • Suitable donor chemicals normally where take H+ ions (or protons).
  • They include hydroxide ions that can be entirely or partially displaced.

By altering the autoionization equilibrium of water (where equilibrium is maintained between water molecules, positively charged hydronium/hydrogen ions, and negatively charged hydroxide ions), bases diminish the hydrogen ion activity in the water when dissolved in it. As a result, adding bases to water effectively raises its pH above the 7.0 threshold.

Summary:

What is the reaction of a non-metallic oxide with the base?

When a non-metallic oxide reacts with a base, it forms salt and water which proves that the non-metallic oxides are of acidic nature.
