Consider the following elements:
Sodium, Sulphur, Carbon, Magnesium
Which of these elements will form:
(a) acidic oxides.
(b) Basic oxides.
(a) Carbon and Sulphur will form acidic oxides. Nonmetals react with oxygen to form nonmetallic oxides. These oxides differ from metallic oxides because they are acidic in nature.
Therefore, oxides of sulphur and carbon i.e. sulphur dioxide and carbon dioxide are acidic in nature.
(b) Sodium and magnesium will form basic oxides. Metals react with oxygen to form metallic oxides. These metallic oxides are basic because they react with water to form bases.
