Why some oxides are basic and others are acidic
In short: Oxygen doesn't always behave the same way. This video breaks down how the identity of an element determines whether its oxide will act as an acid or a base.
Oxides are compounds formed when elements react with oxygen through oxidation. The chemical behavior of these compounds depends heavily on whether the parent element is a metal or a non-metal.
Metal oxides, such as magnesium oxide, are alkaline and produce a pH greater than 7. They react with acids to form salts and water. In contrast, non-metal oxides like carbon dioxide are acidic, resulting in a pH less than 7, and they react with alkalis to produce salts and water. The video also demonstrates how to write and balance symbol equations for these specific reactions.
