Common mistake
Confusing Acidic and Basic Oxides
Students often predict that all metal oxides are basic and all non-metal oxides are acidic, without considering specific examples.
To fix this, students should study specific metal and non-metal oxides and their properties, remembering that while many metal oxides are basic, there are exceptions, and similarly for non-metal oxides.
