SPM Form 4 Chemistry 6.4 Chemical Properties of Acids and Alkalis 6.4.4 Oxide: Basic, Acidic, Neutral, or Amphoteric

Oxide: Basic, Acidic, Neutral, or Amphoteric

Basic Oxide

  1. Most oxides of metal, especially alkali and alkaline earth metals, are basic oxides.
  2. Basic oxides that dissolve in water are called alkalis. 
  3. A basic oxide is an oxide that shows basic properties in opposition to acidic oxides and that either
    1. reacts with water to form an alkali; or
    2. reacts with an acid to form a salt.

Examples:

  1. Sodium oxide, which reacts with water to produce sodium hydroxide
  2. Magnesium oxide, which reacts with hydrochloric acid to form magnesium chloride
  3. Copper(II) oxide, which reacts with nitric acid to form copper nitrate
Acidic Oxide
  1. Most non-metal oxides dissolve in water to form acids, and are called acidic oxides.
  2. An acidic oxide is an oxide that either
    1. reacts with water to form an acid; or
    2. reacts with a base to form a salt.

Examples :

  1. Carbon dioxide which reacts with water to produce carbonic acid.
  2. Sulfur dioxide, which does not form the non-existent sulfurous acid but does react with bases to form sulfites.
  3. Silicon dioxide, which does not react with water but will react with bases to form silicates

Note:

    Not all oxide of non-metal are acidic oxide. For example, carbon monoxide (CO) is neutral.

    Amphoteric Oxide

    1. The metal oxides that can behave as both acids and bases and are said to be amphoteric oxides.
    2. Examples of amphoteric oxides are lead oxide, aluminium oxide and zinc oxide.
