They react with metals and non-metals to form oxides. What are Oxides? The classification of oxides is done into neutral, amphoteric and basic or acidic based on their acid-base characteristics. An acidic oxide is an oxide that when combined with water gives off an acid. A basic oxide is an oxide that when combined with water gives off a base.

Sulfur dioxide is a precursor of the xide (SO 3) used to make sulfuric acid.In the laboratory the gas may be prepared by reducing sulfuric acid (H 2 SO 4) to sulfurous acid (H 2 SO 3), which decomposes into water and sulfur dioxide, or by treating sulfites (salts of sulfurous acid) with strong acids, such as hydrochloric acid, again forming sulfurous acid.
